Not too sure if this is actually hypochondria but here is the story of my Dad. A few years ago he was hospitalized for, according to the doctors, what was probably a viral infection that infected his heart. He completely recovered and is in good shape but ever since then he has gotten sick every year on the anniversary (within a couple of days) of that first illness, and goes to the hospital for major nausea and vomiting. The first year it seemed like a huge coincidence, but after a couple of years it seems really strange, like what kind of sickness flares up like clockwork? The doctors can never figure out what is wrong. I only really started to suspect that he may be making himself sick the other day. He had mentioned his "anniversary" and had said something along the lines of "and what do you know, I have a huge headache". Surprise, a couple of days later he is in the hospital. I don't think that he is faking his sickness, but i am starting to think that he gets himself all worked up around this time of year because of the memory of that first time. I am afraid that his stress and anxiety about being sick is actually what is causing him to be sick. I don't want to say this directly to him, i don't think he will take it well, and i might be wrong. What do you all think?
