Seeking medical help for infections?

Hi, I'm new here. I'm 39 and have always been a picker, could never leave scabs alone, etc. I have severe anxiety and OCD, as well as a long history of self-injury, that had been under control for 6 years. I am still "clean & sober" from self-injury as far as cutting, etc. But this year my picking began to increase and is now out of control. My body is riddled with wounds, scabs and open sores. The worst area is my breasts (I've seen others mention the same issue here). Part of the problem is that it's nearly impossible to bandage the area, and bras rub against the wounds all day, never allowing them to heal on the rare occasions when I can keep myself from picking for a few days. I'm horribly embarrassed by what I've done to my body. I want to show my doctor, but I keep chickening out. I know the wounds are seriously infected, with red streaks connecting many of them, as well as streaking towards my heart. I wouldn't be surprised if I had MRSA. Or was even headed towards sepsis. But not even knowing that is making it easier to see the doctor. Anyway, I dunno. Tell me your horror stories. Scare me into seeing a doctor. Anything. Or how about some advice on how to bring it up with my doctor? That's the hardest. :(
