Hello Bookworm: I'm sorry you are having such difficulty. It is really important, in my opinion, that you share with your parents what is going on with you. Sometimes one way of approaching something like this is to begin by asking one or both of your parents to sit down & watch a video on the subject. The video can then be a starting point for talking about what is going on with you. One possible video might be Kati Morton's YouTube video on the subject of hair pulling:

But also if you go to that video on YouTube you can look down the right-hand side of the screen & see thumbnails for other videos on the subject.

Another possible way of approaching this might be, if you are in school, perhaps there is a school counselor you could see. And perhaps that individual could help you to figure out the best way to approach your parents.

Under any circumstances, I send hugs your way with the hope that you will be able to find the strength to open up to your parents with regard to your struggle.
