I am now having a hard time playing the violin because of the long period of time i haven't practiced. I want to be inspired again by classical music.

This sounds kinda stupid, but to get more interested in classical music (when it's been a week or so since I've played) I like to listen to music, especially Mozart piano concertos and symphonies. I don't know of any good violin pieces, though, seeing as I don't play the violin myself.
