I think it's normal to get anxiety when going into Wal-Mart.
But as far as everything else, I totally understand what you mean. When I had panic disorder, I couldn't believe people could just eat at restaurants with ease. It was so hard for me! Now I can do some of those small things pretty well-- but I never take them for granted because I remember when I couldn't-- and I often feel like I'm hanging by a thread... like at any moment it could be cut and I could go back to that again. It's scary stuff. I still worry about stuff all the time. Obsessions and stuff. Wonder what it would be like to have a clear mind. To just relax.
