A couple times this past week for about an hour I will get an intense feeling that I'm not real and nothing really exists. It came back again today and I feel like I could do whatever I felt like because it wouldn't matter. I've thought about "proving" to myself that things were real but I don't 100% believe it and don't want to permanently hurt myself. It feels like I could just go up to someone and tell them to stfu and punch them in the face and nothing would even happen. I told my therapist about it when I saw her and she said it was depersonalization from anxiety and that she could tell I was extra anxious/fidgety. What could I do to help with this feeling?
