Is it worth living?

I'd say just try to get into something that interests you and try to make your life easy for yourself. Like just spend your spare time playing video games or writing or whatever and don't force yourself to do much more work than you feeling like doing. From there, build some good habits like healthy eating (if you're not already) and enjoying nature. Make some friends who you can be with when you're lonely. Phone a psychiatrist if at all possible and work with them on treating you.
