I can't stop chewing my fingers to the point that it is full of painful calluses and my head is starting to hurt whenever I chew nonstop. I do stuff like 'rituals' but not out of being superstitious, like doing things three times or whenever I look to my left I will have to look to my right for no reason. I do hate certain numbers like 2, 4, 6, 7,8, 9 and 11. I also often use a lot of alcohol. I just want to know if I really do have an OCD or I just need some self control.
