new to the forum: I pick my scalp & play with my hair

Hi. I'm new here, just found this forum today. I am 33 yrs old and I cannot stop picking my scalp and more so, I play with my hair ALL THE TIME. I do not think that I have trichotillomania because I don't actually pull my hair out, I just fiddle with it and run it through my fingers. I have long hair, except for around the crown, where the hair is only a few inches long, caused by me playing with it which breaks my hair off. Not to mention, I have started to get extreme pain in my wrists, elbows, and shoulders from the repetitive movements. I never had this problem as a child, it started in my early 20's and then stopped a few years later. Then it started again at age 30 and this time it came back with a vengance! I feel like I really cannot stop, I am so frusturated. I am so ashamed and embarrassed that I do this. I have been seeing a psychiatrist since I was a teenager for depression/anxiety. But the scalp/hair issue is a rather new issue and it continues to get worse. I never noticed how much I did it until people at work (I am a nurse) started to make comments to me like "why do you play with your hair so much?". Every fews days, a different person at work will make this comment to me. I am so humiliated that so many people notice it. Why are some people so insensitive? I would never ask anyone a question like that. What do they expect my answer to be???
