HELP I just cant stop pulling my hair?

I have been compulsively pulling my eyebrows out for over a year and for the last few months my eyelashes and scalp hair too. I shaved my eyebrows so there isnt any to pull but I still have this disorder. I have always had anxiety and some repetitive body behaviour like i didnt stop thumb sucking until i was 14. It just makes me feel much better to do these things and Its so hard to stop, almost impossible
