Help

I've never gone to a doctor or a therapist to see if I have trichotillomania... But after reading trough some of the posts on here I'm 99.9% positive that I have it. I've been dealing with it for about four years, I was 13 turning 14 years old. I am almost 18 now. I imagine a future everyday where I can just let my hair down and not have to cover certain spots. When I first started pulling it was on top of my head where there was a sore spot (for some reason those seem to be the best spots to pull) I ended up with about a quarter size bald spot. When it was that small it was very easy to hide. Then I started to pull around the bald spot and then the bald spot gradually ended up being about the size of my fist. I still am able to cover it -- I have a lot of hair. Well I don't have a bald spot anymore but I still pull and the hair that has grown back is in various lengths because of pulling and cutting it to my scalp -- my hair that has grown back isn't smooth like my other hair, it has a ruff texture (which makes me want to pull it out even more) and the hair that has grown back is fuzzy so if I don't braid my hair and just have it in a pony tail it's super noticeable that I have some weird hairs. I want to stop. I pull when I'm watching tv and I yell at myself every time. If I didn't love with my parents still (still in high school) I would not worry about hiding it at home. I hide it from my family. My mom knew when I first started and she didn't know why I did (neither did I) she doesn't know that it I'll continue to pull. She thinks that it was just that one time. It would be nice if I had daily motivation to help me stop.
