Could yours be anxiety-related?
I have White Coat Syndrome, so almost every time I go to the doctor I am asked about my blood pressure and have to explain that it's just anxiety.

“Still and all, why bother? Here's my answer. Many people need desperately to receive this message: I feel and think much as you do, care about many of the things you care about, although most people do not care about them. You are not alone.”
~ Kurt Vonnegut
