I'm losing control of my life.

I'm suffering from severe depression. Back in June I had a mental breakdown, which caused me to lose my job, my home, and one of my best friends. I was sent to a hospital to be helped with my depression. Since then I've been trying to find a job, make therapy sessions, and get back on my feet. My dad gave me his camper for me and my dog to stay in but he is losing patience. I'm almost out of money to keep me and my dog fed. I've resorted to not eating so that my dog can eat. My dad has given me to the end of August to find a job and to support myself or else he will take my dog from me, and kick me to the curb. I've got tons of medical bills piling up, totaling to upwards of $12k. I'm signed up for medicaid, but it was issued after the billing period started, so they will not cover it. I don't know what to do. I've been applying to multiple places and following up on all of my applications but can't seem to find a job. I can't pay the medical bills and cant see any option for that. I'm pulling my hair out trying to get back on my feet but all my dad sees is his loser son failing at what he refers to as a "simple task". I have no one else to turn to and see nothing good in the near future. I'm only 20 years old, fresh out of high school, and I've already destroyed my future. I don't know what to do anymore. The only future I see is killing myself but I can't bring that burden on my family and friends. I just needed to vent this. I don't know what I'm gonna do.
