I am also a hypochondriac and yes mine did start after the death of my mother. My mother was chronically ill and once she passed away every change in my body I would freak out about. I am slowly getting better dealing with it. As I type this I am going through an episode of it now. I have something inmy mouth so I went to the Doctor here in Hong Kong and maybe because I don't trust them here that is why I am not convinced by what he said it was. Anyways, my point is you are not alone. I do believe it stems from anxiety as well. If you need to talk we are all here for you. Hoped this helped a bit, if not at least I tried right?!
