I wanted to ask here as I’ve found no luck elsewhere. I just wanted to know if this was a common thing among other people with anxiety.

Sometimes, when I’m so overwhelmed with my work, I can’t speak. Frustration, upset, uncomfortable, anxious… I lose my words and I end up trying to use my body language instead.

Eventually, when I’m really broken down, I end up hitting/ punching my legs, scratching my arms, and tearing out my hair. It’s all because I simply can’t talk it out with someone, and that’s what frustrates me even more.
In those moments, it feels as though I’m a child having a tantrum again- it’s embarrassing.

I don’t know why I can’t talk in those moments, or why I resort to physically beating myself up over it. 
Idk if I’m alone in this. Maybe others have had a similar experience? I’m wondering if there’s a better name for this kind of action, too.
