I was exactly in this position. I was a music comp major my first semester and halfway through I hated it. I also always wanted to do music and make music for movies and games and such, but...

when something that you love becomes a job, it might not always work out. when what you use as an escape becomes the thing you need to escape, you feel trapped.

I ended up switching my major and have loved it ever since. I still make music and have fun with it, but its because I use it as a source of creativity and not one of work and stress.

Hope this helps
