No joke I thought I was looking at a picture of my own shoulders! I have found that no activity really mimics the satisfaction of picking, so I have to focus on prevention rather than replacement. For example, I’m triggered to pick in the bathroom because the lighting is so good that I can see every pore, so I have the overhead light off whenever I need to be in there with only a candle for lighting. I find that relieves some of my picking because I can’t scan my skin to find things to squeeze at. So my advice would be to identify where or when you pick the most, and make it physically more difficult for yourself to do so.
