I'm just beginning my battle with whatever the hell this is (undiagnosed), but I can relate to having anxiety attacks all day long. I have struggled with PTSD, anxiety, and depression for the last year and I know it's very hard to deal with, especially when you have physical problems that seem to only exacerbate your anxiety.
If you ever want someone to talk to or chat with or anything, let me know. I'm more than willing. Just know you're not alone.
