I share your pain. I have severe health anxiety as well. I haven't felt safe for last 2 years. The fear that something bad ( some terminal illness, like cancer) will happen never leaves me. Every breath is full of caution and paranoia. i'm afraid to dream and hope, coz it all seems pointless, the mind is convinced that it'll all go bad no matter what i do. I'm fighting every waking second to calm my mind and pacify the worries. But it never ends. One worry is replaced by another.

The most helpful tool i have found that helps me get through everything is by relating to other people. Say my mind is convinced that if eat eggs, i'll get cancer, so i look for people who eat eggs everyday and are healthy. Like i researched John cena eats 8 eggs everyday. My mind calms down once i know there are other people who share similar beliefs and habits. I'm afraid running will ruin my knees, so i look up people who have been running everyday for all their lives and still have healthy knees.

I have started prozac two weeks before. Cant say it has helped so far, but its too early to tell. I was misdiagnosed for a long time, docs thought i had bipolar 2 so they kept focusing on fixing my moods rather than my anxiety. This is the first time i have a clear diagnosis ( hypochondria) and have started a targeted treatment.

Choosing what you focus on every second will make all the difference. I just keep reminding myself that " all i need to do is run towards the light" and there's always light, no matter what. Dont focus on the darkness.
