New here and need some comfort

Hi everyone. I've finally broken down and decided I need to speak with others who are suffering like I am. I started picking at various places on my body when I was around 12. I pulled off my toenails and went after my face and chest. I have other mental disorders that exacerbate the picking (including OCD). Over the last year or so, my attentions have shifted severely to my legs. They are red and scarred all over. I even had a bacterial infection. I've started going to a therapist and discovered that basically, because I've had mental and physical issues for most of my life, I never really developed a non-destructive way to self-sooth. I so desperately want to stop doing this. Not necessarily for vanity's sake (though I am a model and it certainly hinders my progress there) but because I find it so mentally distressing. I decided to join today because I just picked for 40 minutes and I feel awful. I just want to forget my legs even exist. I know relapse is a part of recovery but it's really difficult to see it that way when you're in the middle of it. Just knowing that there are others out there suffering like I am is a bizarre comfort. If you'd like to share your experiences with relapse, please do. I need a little encouragement.
