Hi. I'm new here.

I do something really embarrasing in therapy sessions. Sometimes, when I get really nervous or upset, I will scratch/pinch my arms or knees. Sometimes I have bled. It is an immediate reaction, so generally I do not realize I am doing it, and when I do realize, I just can't stop. I know my therapist can see it, but she doesn't say anyhting (which is good, because it would make me nervous). She knows I sh out of therapy and she was really nice about it and told me that now it's helping me cope, so it's okay

I was wondering if the sh in therapy is a normal thing? Do other people do that in therapy sessions? Does your therapist say anything? Should I say something about it? I get really nervous (shake (sometimes violently) and fidget during therapy)
