Mamacita,
What you said concerning self diagnosis (typically through Dr. Google) is very prominent on the health anxiety forums. Added to that, phobias of tests, dentists and doctors adds up to one big mental mess!
As I researched and read over the last few weeks, I've been taken back by the sheer number of people and the plethora of issues that exist. From general anxiety to full blown panic attacks to OCD, social and health anxiety, phobias etc. Some posters having several of these issues at the same time. Also, many posters suffer from IBS (Irritable Bowel Syndrome) which is aggravated by their anxiety. I'm just thankful I don't experience the issues I've been reading about. I have enough to deal with just recovering from treatment
Thankfully, there is help available. From self help suggestions to therapy and Rx drugs to help control symptoms. On the opposite end of the spectrum, there are several threads that offer hope for those suffering from these maladies.
Positive thoughts and prayers
