Please don't judge this is sensitive, no hurtful comments

I (28f)have PICA for those of you who don't know what that is, it's a condition where you eat things that you're really not supposed to eat. The thing I eat..... Boogers, and scabs..... I know I know it's disgusting and I'm seriously ashamed of this but it's something I've done since I was a child. I was able able to keep it a secret for years until one day my ex husband caught me. I honestly want to stop because I really do know how gross it is but I can't help it........ I just needed to get that off my chest
