I have anxiety and depression, panic attacks and I self harm. Yesterday was going ok until in the afternoon I started to feel anxious and upset but instead of having a panic attack or managing to calm down, I sort of shut down and was almost in a trance. The friend I was with at the time said I just sat and didn't move for ages like I was frozen. I wasn't deep in thought and it just felt like I wasn't there and that I was detached from everything around me. I found it really really scary! Is this part of anxiety? Does anyone else get this?
