I'm not sure if you all know about this website, it's called anxietycentre.com. It has a list of symptoms caused by anxiety, it really helped me to understand everything I was feeling was because of the anxiety itself. There's so many symptoms on there that I would never think of being caused by anxiety. I had sharp pains in my head and believe me I thought it was because I had a tumor. Sure enough it wasn't that but I couldn't stop thinking it was.
I'm 2 weeks into being free from the attacks, so I hope this helps you all. Best wishes and God bless.
