Stress affects nearly every aspect of your life. The key is to use the good parts of stress (good stress can be the key to motivation), and lessen the bad stress.
1. Keep a good schedule; get the amount of sleep you should be getting, and stay on schedule. This includes eating appropriately and drinking plenty of water (leave the soda pop for someone else).
2. Take the time to get organized. This alone can relieve a lot of the problems that trigger stress. Make the best use of your time, avoid time wasters such as TV and video games until you have figured out a manageable schedule that lessens stress.
3. Analyze what is going on in your life and figure out what may be causing your stress. Are you reacting proportionately, or can you de-stress by taking a different attitude.
4. Talk to someone you trust. Share your feelings, and get a different perspective on things. Be willing to listen with an open mind.
5. Take some time for quiet. Use this time for reflective thinking, prayer or whatever method is good for you. Quiet your mind and let your body follow. This can be a very hard thing to allow yourself to do, breath deeply, let your mind see simple, serene images.
6. "Self Talk": tell yourself how good you are, how great things are, how you can do it, how great you feel, what a wonderful day it is, what a great player you are = all GOOD POSITIVE things. It can do wonders!
7. If your flute playing feels not up to par, then spend some time playing a well loved (known and easy) beautiful piece that brings you pleasure. Play along with a recording or the radio, "jam" and just have fun for awhile. Spend some time on long tones and what I call "free playing", just play a beautiful combination of notes.

You are a student, right? You are probably being piled high with assignments and projects. There are always dramatic things happening in a student's relationship life, these things have a way of working out, really they do. If your stress becomes so overwhelming that it takes over your life, or if you feel very desperate and hopeless, be sure to let you folks know, and seek the help of a professional such as a counselor.
Take care of yourself, and things will turn out alright.

Well, without knowing how it's affecting your playing, or even what kind of stress you're under, it's impossible to know if stress is indeed the cause, or what can be done about it, besides telling you to remove some of the stress-causing factors from your life.

Personally, I find playing much more relaxing than other stuff. Right now my life is crazy.. i have 3+ hours of homework every night (with a study hall..) and i have two instruments to practice, getting ready for all-state for both as i haven't decided which im going to do yet.. Im busy every night after school (Mon from 4:43-9:00, Tuesday lesson from 4:45-6:30, then from 7:00-9:00, Wednesday from 6:00-8:00, Thursday lesson from 4:00-5:45, and Fridays will be football games, so Marching Band. (all of those include the 30 min travel to things..) And im getting pretty minimal sleep. Thursday night i got 5.5 hours of sleep, which was the least this week. 6.5 was probably the most.

If you don't already, try to start your homework as early as you can. I know I need to do this, but i hate coming back from school just to do more work.. but lately that time from school to homwork which is usually 7 or 8:00, (but im going to be busier starting this week..) im practicing, not watching tv/internet like i always did last year.

And definately just take some time to relax. Find something relaxing to do for a while- read a book, listen to music, watch tv. Don't do that.. excessivly if you have other work that needs to get done but ya Also when your working on homework, take a some 5 minute breaks (I need to do this too :P) every 30-45 minutes.

Sounds like you need to talk to your parents.

While I doubt that the reasons that your teacher failed you are your nationality and trouble seeing a board clearly, it certainly may seem so to you, and it does happen occasionally. If you're convinced that this is the case, and have some evidence to back your feelings, you might consider taking the issue up with the administration at your school, or local school board. Unfortunately, without a better understanding of your life (which would be difficult to gain through the internet), it's very difficult for any of us to provide suggestions for isolating whatever is causing you stress. It sounds like you have a pretty good idea, though, so keep this in mind....We choose our attitudes. If something is inevitable, stressing about it won't help anything, so why not choose not to worry? Or as a movie I was recently introduced to put it, "Worrying is like a rocking chair. It gives you something to do, but it doesn't get you anywhere."

"(She faild me for bieng russian, and having hard time seeing the board form the back of room)"

Lera, Don't get stressed out about it. Do something. If this is the case, your parents should go to the principal or maybe even higher up in the school system to seek help. The teacher may not be willing to resolve this issue but they may be required to cottect it or face disciplinary action. They may even change teachers for you.

If you feel discrimnated against for nationality or race reasons, it is serious for this teacher. If you can't see the board then the teacher should help by moving or suggesting that you be fitted with glasses or cotacts for your eyes. Any decent teacher can tell if you can't see the board, you'd squint your eyes when you try to read.

Lera,
You may also qualify for services as an English Language Learner (ELL), (different states may call this service by different names i.e. ESL, English as a Second Language, or other names).

What course (class) was this in? It very well may be time for your parents to have a meeting with administration/counselor/student services, whatever your school calls it.

As the previous poster mentioned, since school hasn't even started yet, perhaps you really don't have anything to worry about.

If you are having to re-take this mandatory class, you may be much better off the second time around, since the material will be more familiar to you. Also, you will have the added bonus of EXPERIENCE this time around, more familiar with the material, AND knowing what to expect from this teacher. Be proactive! Approach the teacher with an open and positive mind, express your desire to do well.

Be sure to communicate with the teacher anytime you find yourself having problems or getting behind. Teachers love this type of student, however, they do not like a student who doesn't take responsibility, plays like a "victim" (it's always somebody else's fault), or has a negative/disruptive attitude and behavior.

Be an eager learner! Request an upfront seat, figure out went wrong last year, and do things differently this year!

These are life lessons that will help you in the future, as adults have to learn to play the game everyday at work with coworkers and bosses.

Lera, very sorry to read about your problems at school. I could not imagine them before your explanations. When I was a child, decades ago, I had (a bad) teacher that used the placing of pupils at the back of the room as a way of punishment. It happened to me once and it was so hurting taht I still remember it vividly. But, normally some have to sit at the rear, or at least not in the firt line, for space reasons (although the arrangement of the classrooms has been deeply modified in modern times). So it should not be taken as

I cannot help about this as I do not know the US system and also because it has been such a long time I went trough this kind of problems...

I feel happy however to notice the wave of warm helping people counselling and trying to provide useful ideas. It really speaks very well of the group of flutist that has gathered in this site.

My humble help, away from trying to improve the school conditions surrounding you is to trust on the capability of music to help even in the worst situations. Stress may affect your playing, yes, but I have no doubt that the moments you can spend performing or practising the instrument will help in alleviating the stress.

We all suffer from stress from very different reasons; I am not an exception and I have plenty sources of heavy stress now and then. This sometimes reflects in increased blood tension, eyes problems and other difficulties. But music has always helped me in those moments; it is important, in my opinion, to be able to set aside a moment, every day, to do what helps you (such as flute playing); this will not solve the surrounding problems, but it will help you in dealing with them.



<Added>

sorry I was interrupted for a long and stressing phone call and my post was sent truncated.
I meant:
So it should not be taken as = so it should not be taken necessarily as a sign of rejection.

if you can't see the board you need t o go to the optitions, but other then that just keep to your self don't give her any reason to fail you, find a way to vent out all your stress after school, like playing a sport you enjoy, or play a song, or simply count to ten and relax
