This made me feel better to some degree, because the same thing occurs with me. If my heart failure is not making me feel awful, this arthitis I have keeps me in pain 90% of the time. And most often the both are active at the same time.
I know we are not supposed to complain, so we tend not to, except sometimes to each other. Anyway, I try to apologize to people and snap out of it as fast as possible.
I need to do better.
