just dropping you a reply because i feel your situation completely. i'm 22, working at a job and i'm not in college anymore. i broke up with my boyfriend and i feel your pain.
going back to your doc is a very good idea, seeing a therapist is a very good idea. look into that stuff.
this is such a tough time in our lives, you gotta do whatever you need to do to keep your head above the water. i hope i dont sound cheesey i'm just trying to inspire you, make sure u know youre not alone.
go to the doc, and get the meds if you need it. let him know how much they helped. good luck
