How can I reset my life?

I need some insight on a strange ,but I would like to think not that uncommon, problem. I was the life of the party, original, highly intelligent, and artistic crazy guy that everyone loved. Then I met the one original, not common, artistic girl, and spent 4 years with her. We lived life differently than most common folk who commute to their dead end jobs, making havoc and chaos like anarchists, enjoying the small things in life, adventuring on rooftops and into abandoned buildings. We wrote, drew, painted, life was good, something that most only see in books or movies. But then it fell through, I lost a lot of personality and my love for life, and started drinking, lowering my IQ. 2 years later I'm trying to revive my old self, but it's too late, she got bored of me and found a version of me 2.0 and I lost all of my old friends in the process of being with her. So here I sit, trying to get back my personality and my intelligence which is getting better, but then everything in my life is making me unenthusiastic to do so. I have no job at the moment because i was fired, Can't pay rent this month, lost my car, can't find a job, no friends anymore, and my old love hates me, which sucks more because I live with her so I just get to have all this terrible storyline rubbed in my face daily. I just need an Out, a reset, a new life. I've tried it twice before but failed. I need a traveling job, or somewhere i can go with no money and start a new life, work abroad, anything. It's between killing myself and hitchhiking, and I don't really want to die, i want to live, i want to love life again, I mean I'm smart, only 21 years old, and very good looking, just I've lost how to live really. And I'm sick of this moment, it feels like it's dragged on for years. Just give me comments, ideas, job offers i can leave my state of Texas for, anything to start over. Even flames, hell go for it. Hitchhiking is looking the best bet so far after i save just a small amount of money. And don't give me "don't kill yourself" comments, that's not what I'm looking for. And no, I don't have anyone who wants to listen to my problems and help me, so I look to the internet to hear me out.
