So most likely I'm just over reacting but I have so many things that set off my hypochondria. Like for instance when I walk or run I get a clicking in the top of my head that I can feel and hear. If I have a cold or something like a flu I'll be convinced that I have Lung cancer or HIV. I know it's stupid but this is honestly taking over my life and I'm scared about my health all the time. Anybody have any ways of coping or advice?
