At your age I was working in a bookstore for 7.75 an hour. After that, I worked a graveyard shift at a residential treatment facility for 11/hour. Since then I've built and sold companies, raised venture money, etc. I started the good stuff near the age of thirty but I enjoyed the low-money years.

Step one is getting yourself happy. Punt the toxic people in your life, focus on friendships, exercise, and mental health (it sounds like you're depressed), and save up a few nickels. There'll be time enough for financial ambition down the road.
