I had my first manic episode when I was 19. I'm 34 and still dealing with my issues. I live with my parents, in my culture it's okay and when I was working I help with bills so no shame in that.
I'm in your position because I fell into a deep depression in November. I resigned from my position this month. I'm home and keeping busy but no job yet. I'm hopeful things will get better but they will only get better if I do something about it.

Seek therapy, take your meds and work on getting better. Once you have taken care of yourself figure out what you want to do be it school or a job.
