I just got back from my therapy session and my T decided that we should do something called PE in order to get over some very serious anxieties I have. She warned me that it would be scary and hard but that it's a proven method to help get over phobias and trauma. She told me to do some research before our next session next week and I'm searching it up but getting more worried because of what might happen. Can I stop at anytime if it gets too hard?

If anyone has had experience with it can you please share what goes on? Thank you so much
