Arms and back picking

I am incredibly desperate. I have I have been picking for 15 years. KP spots, hair follicles, scabs - you name it. I have tried medications for acne, medications for anxiety, supplements including NAC, wearing long sleeves, taping my fingers/cutting my nails.

At this point the compulsion and NEED to pick is interrupting and interfering with my daily life and not to mention the physical damage and pain.

What’s worked for you?
