Re: Dropping out of school, drumming, and mental health (sort of)
You should find somebody else to play with, you've got to keep that creative outlet open. Even if it's not a gig your totally into it's better than not playing with other people.
Is there any possibility to work less hours? If there's not maybe you should find a different job that allows you more time to pursue your music. If your not planning on staying at that job for the next couple of years it's probably not worth killing yourself over it.
Keep your head up, take things one day at a time. Time is the only thing that is going to help with your ptsd. I know what it's like, and sometimes you just really need something in your life to take your mind off things.
