I think that it is more from anxiety. But I do hear in your post a theme of not taking good care of yourself. I have never heard of anyone being hospitalized for picking at themselves. I also agree that you need to tell her so that she can help you with your anxiety. Have you all been working on your anxiety? I don't think that she will do anything that will change your life for the bad. She just needs to help you.

I recovered from anxiety so I can share what I did if you are interested. Please keep us posted?
