I went through some of the same things you are going through and because I was worrying about my health all the time I got depressed really fast. I was having emotional breakdowns, didn't want to do anything, couldn't go to work, couldn't live my life.

I went to two docs and both said it was anxiety mixed with depression. I accepted that and immediately started to feel better. They gave me some meds for it- celexa and klonopin which has really helped.

I too could not believe all my symptoms could come from anxiety because the drs didn't really explain it to me. The symptoms are very real, they are not in your head, they are physical but they are caused by health anxiety and or depression.

I found the medicine has helped quite a bit. If the Drs tell you its anxiety it probably is. They know what they are talking about. The hard part is accepting it so your brain and body can start to relax and recover from all the stress that has been put upon it.

My symptoms aren't gone but they are a lot better.
