I feel really bad. I always skip my only friend’s birthday parties. I have tinnitus. It causes me a lot of stress, and I can’t be in loud environments. So I skipped her parties at bars etc, but she recently invited me to a cafe birthday celebration, and I turned it down (and explained the honest reason why and added that I wanted to treat her to a lunch nearby alone and I got her a present.) I feel so bad and I’m cringing thinking about her possible reaction. I also have ptsd and several anxiety disorders. Being around people I’m not close to makes me very anxious and there is always a group of people at her party. I actually don’t want to hurt this friend and I spent a really long time, with a sprained ankle, picking out her presents. She’s my only friend, actually. I have no social life. I don’t want her to hate me. But I have anxiety so bad I vomit daily some weeks. I am afraid I am sounding selfish and that she is secretly mad at me. Can someone please help?
