Serious answer:
It sounds like you have a real problem. You NEED help. Treat it like alcoholism, or any other addiction. Look into the sorts of things that have worked for others breaking an addiction.
I am guessing that your personal hardship is making this even worse: You turn to SP's for comfort when you feel bad, your personal situation is bad, you turn to SP's to feel better but that just pushes you further into debt and creates further problems, which makes you feel worse, and on it goes in a downward spiral. You need to break out of that.
Try and find someone in your personal life that you can confide in. Someone you can call and talk to when you think you might be on the verge of doing something stupid. Meanwhile rip up your credit cards and do your best to put your money beyond reach--put it into a savings account that requires a day or two's notice to get it out and destroy your credit cards.
Try and stop cold turkey. Try and develop a feeling of pride when you overcome your urges, learn to feel that it shows you are in control of your life.
Most importantly find a substitute activity. People have been suggesting a girlfriend but that's not right--you aren't seeing SP's like this just because you need the company of a woman. You may feel you are, but you likely have deeper issues around your self image. Try and make new friends, join a club, create opportunities in your life to feel a sense of achievement and satisfaction that have nothing to do with women. Don't NOT get a girlfriend, but don't make another person outside yourself the solution to YOUR problems.
I'm not going to say that using prostitutes is wrong and that you should never do it again in your life, but you are letting it take control, and you are using it as a substitute for something more fundamental. Some people drink responsibly, and some people use alcohol as a substitute for solving the real problems in their lives. Same with sex for money: Some people use prostitutes responsibly, and some people use it as a crutch, and become addicted to it. At the very least you need to straighten out your life before you get anywhere near an SP again, and maybe if your behavior is destructive enough you should call it quits for life. I don't know, only you do.
In the meantime look at what alcoholics do to cope with their addiction, all addictions are fundamentally similar.
Take it one day at a time.
