breaking out of this cycle

So this is my first ever time reading and writing on an online forum about skin picking and first ever time creating a pseudonym! I'm doing this because I can see how the skin picking is part of a self destructive cycle which is my lifestyle. I have tried a few different things to stop my skin picking, which I guess started when I was 13 (I am now 19). It began when I was I was really nervous about starting school after the summer holidays I just started automatically scratching my scalp and creating scabs which I would pick too. Then it sort of settled down and came back again with a vengeance when I experienced very severe depression, where it progressed to a catatonic level. I had no concept of time, I would forget to eat or drink and would just sit in my room scratching my back. I have some real scars to show for it. I came out of that depression and was ok for about a year then experienced acute psychosis, maybe marijuana induced, but mostly due to earlier trauma of my dad deciding he wanted nothing to do with my life (this was when I was 13). I understand the psychosis I went through a lot better now and am in a relatively stable part of my life, I am at university and have some great friends but this skin picking just won't stop. Since my psychotic episode when I was maybe 16 I have skin picked constantly. At first I would hide it from my family but then I opened up to my mum, see she would see my habit and think it was a subconscious thing I did and all I needed was being told to stop, what she didn't know was that I actively did it and enjoyed doing it, it relieved stress, as I'm sure a lot of you can relate to. So then my mum and I searched for what help there was out there. We found an NHS funded clinic in London which specifically deals with skin picking and the psychological aspect of it. I have had a number of therapists/psychiatrists in the past for my depression but have found none of them helpful. I went up to London once a week for my skin picking therapy sessions, it was a CBT method. It was useful in the sense that I was able to actually tell another person aspects of skin picking that I even tried to hide from myself, like that I enjoyed it, that it was a form of self harm and that I used it as a way of protecting myself from sexual experiences and the rejection, pain that can come along with it (I have had my fair share of not very self respecting early sexual experiences). I found that by having a horribly red spotty bikini line it gave me a reason to hermit myself and shut off from this part of life, but of course at the same time I felt sorry for myself and wished I could date, have a relationship etc. However the therapy course didn't help me stop. I still pick and what angers me the most is that it is me who is doing this damage so it is me who can stop! Now I really want to stop. I am shaking up my life, changing these habits, and one of these ways is by writing here. I would recommend to all skin pickers out there to wear gloves when you go to bed, and when you are on the computer or reading, for me these are the times when my hand wanders to my face and I can't stop picking. Also I find that my finger tips play a very strong role in my picking, the sensation of feeling the dry skin on my face and peeling it away is part of the enjoyment, so by wearing gloves my finger tips cannot feel my face and this actually dampens the urge to pick. I am about to start a 3 day challenge (30 day seems like eternity!!)
