I have suffered from health anxiety on and off is say for the last 9 years: mine started from a panic attack I had when I was 17 years old, first one I ever had didn't know what it was etc. So that's where my heart worries came up. I suffer from OCD aswell so I think over the nine years I have had health worries some have never came around again some have repeated my anxiety has told me everything from HIV, brain annuresym, melanoma, lymphoma, several cancers, heart attack, DVT, diabetes.
I'm now at the stage where my anxiety has got so bad I suffer from very severe depersonilation and derelisation. Every feeling I get wether it be lightheadedness, to a slight pain in my finger I think I'm dying.
But I have started counselling now and CBT so I'm hoping to get better.. And live my life again without fear I'm dying all the time.
