Sorry you feel that way. I had some problems like that a while back ( well, let's not call these things problems, but a symptoms), and what i did was put on headphones and relaxing music and went for walks. I also focused my attention on certain things like how the air smelled, how the clouds looked, and how the ground 10 feet in front of me looked. I just tuned out the rest of the stuff, and it actually seemed to work for me. There were a few times i didnt feel comfortable, but usually turning down the music a little helped.
Anyways, just some ideas.
Also, recently i had a bump in my recovery and had extreme anxiety and some panic. I FORCED myself to go out. It was soooo hard to do, but I was just frozen inside like a deer in headlights. The movement helped and i felt better once i was out. If you want to give it a shot, here is another suggestion. Tell yourself a few things, like this. "Ok, I'm going to go for a walk. No one is talking about me, it just feels that way to me. Its ok to have these feelings, and I'm going to try and walk." Ok, so if you make it out the door, you can then repeat to yourself something along these lines " Ok, i'm now walking and I can turn around at any time. Its ok to feel how i feel right now, and its ok to turn around and go back inside.". If you continue to walk, just simply remind yourself that you can always turn around, or maybe even set a small goal "I'm going to walk to the corner and back, if i dont make it all the way there its ok to turn around, and its ok to feel this way. I'm am trying, and it is hard. I will try again soon".
I dont know if this helpful at all.
hope you start to feel better. a good friend of mine is going through the same thing right now, so i'm trying to help him through it. Take care, and be kind to yourself.
