I’m a prostitute and I hate myself, what should I do?

I am 21. I have two beautiful little girls. I take care of my daughters. I have been divorced from their father for two years now. I finally have my own apartment but I neglected to mention that my marriage was hell.
My husband hurt me every way a person can be, physically, verbally, sexually, and emotionally. He left me for another woman when I was seven months pregnant and he is hiding from paying child-support. I don’t know where he is and I want it that way.
Since then, I have seriously become a whore. I got married when I was sixteen and my husband was the first man I had ever been with. I was always faithful to him. I figured that I was just on the rebound after the divorce and that it was only a phase. I don’t think so anymore.
In two years and I have had six boyfriends. Also, I date a lot, which I choose not to count. Every time a relationship take a turn towards serious, I sabotage it.
Also I’m addicted. I smoke, drink, play pool, and get paid for it. I love wearing my underwear in front of strangers. How odd. This is going to make me sound like a *****, but I am most definitely the best looking waitress in the restaurant where I work. Just a big fish in a little pond I suppose.
Last night I lost my phone, again. Also, I lost my wallet, money, one bra strap, and one high heel. I don’t drink often, but EVERY time that I do, I get **** faced. I black out.
It is scary, embarrassing, and it is becoming a serious problem. I have blacked out at least sixty times in my life and I feel myself getting stupider with every hangover. I hate waking up and asking my friends what I did, or who I did. I don’t want to be an alcoholic. I feel out of control.
Pretty much I feel dirty. My morals have gone out the window. I can still say that I am a honest and kind person, but I have been a real whore. I don’t believe in God and I really hope I’m right.
Am I a whore? Opinions vary, but I feel like a slut. Why is it that despite the fact I want to be a good person, I drink and flirt way too much? What is wrong with me?
Please, I would really like to hear someone’s honest opinion.
