Stress Picking

I usually pick at small skin tags and scabs when I am stressed, which leads to scarring and bleeding. The worst is picking when Im at work, because I know its a nasty habit in general, it just looks bad, and if I pick a scab and start to bleed that makes it even worse. Anyhow, the other day I got a large blister on the bottom of my heel and it was so painful that I had to get my boyfriend to pop it. Turns out, it was a blister over a blister over a blister. Once they had been popped, I had a bit of tenderness in my heel, but it slowly got better. Unfortunately my stress picking got the best of me, and I ended up picking away at the three layers of skin that were the blisters... Now I have a very raw, very large sore patch of new skin on my heel, and the pain is excruciating. I resorted to hobbling around and finally put some lotion on it to sooth the dryness, however... nothing has helped for the pain. If anyone could give me any input on what to do about this please let me know! Ive been trying to keep busy all day to avoid picking at the other skin around what Ive already torn off.. but its hard because of the pain. I cant ignore it.
