Depression overload

I need some positivity. I quit my smoking weed and became clean so I could get a job grow up and do something with myself. I got a great paying job with Benny's and everything (for a 19 year old) I was ecstatic. Today was my first day and I got there 20 minutes early ready to start my first day and the boss takes me into his office and tells me I didn't pass my drug test and he doesn't need me. My life feels like it's over, I can't get into an appartment now, I'm jobless and live in a trashy run down place with my boyfriend. I need some friends.
