Believe me, I was pretty depressed four years ago. Graduated college 6 months before, had a well-paying temp government job that ended (and everyone said "once you're in the government, you're 'in'"), switched to the early morning pfresh push team so I worked weird hours, hated my roommate, couldn't pay rent on time, loaded up on credit card debt, got on a final warning for telling lewd jokes, got in trouble for posting something on Facebook, did crazy things with strangers, cried randomly during work, hell I banged my head in a wall during work because I was so frustrated; was miserable, sad, depressed, and lonely. Almost jumped off a bridge at 5am on my way to work one morning.
Decided not to. Took maybe a year but things became much much better. I would have never been able to see what I have become now if I made that jump. I love my job(s), love the people around me, but most importantly, I learned to love myself.
