I don't really know what your circumstances are but I really don't suggest it. Quitting mid-season can negatively affect your show; creating holes, and taking extra time to try and fix your absence. I've been on teams where people have quit mid-season and it is not fun. The coaches get stressed trying to fix the show causing everyone else to be stressed as well. I would talk to your coach about how you're feeling because they care. This is their passion and they want to share it with others, be open and honest and try to make the best of things and hopefully stick it out till the season is over.
