trying to wean off meds - any "natural" ways that have helped the picking?

Well, this is my first time here. I'm 29 and have been picking since I was a kid. It used to be just my scalp (the school nurse gave me funny looks when doing the annual lice check), but has gradually become my entire body. I also have anxiety and depression and I guess this skin picking thing is a type of OCD. Whatever, too many labels. I have been on so many different meds. The combo of Prozac and Risperdal - really the Risperdal - helped a me a lot with the urges. But now I want to get pregnant and don't want to expose a baby to that (even though the docs really want me to stay on them) so am weaning off. The picking is getting terrible:( Anyway, just wondering if anyone had any ideas on other ways to decrease picking. Or any ways to help heal the wounds more quickly so I will have less to pick at. We are supposed to go on a cruise in June and I want to be able to wear a bathing suit! Thanks for letting me vent - it is nice to know I am not alone - even though I have never actually met another person with this issue.
