I also suffer from a similar habit. I squeeze my facial skin. I started treating this disorder after I felt everyone was looking at me as a strange person inflicting self injury. It took time for me to understand everyone’s looks, just after my friends told me a few times to stop doing it. It was so embarrassing that I had to do something with it. A combination of CBT and SSRIs improved my condition very much. Do you also feel everyone looks at you as strangely?
