My anxiety has eased. (Thank you, Platinum Heart.) I have felt home-bound by my mental state and the heat. I have a very rapid heartbeat. Doctors just seem to shrug when I tell them about it. Some say it is from anxiety. Some say it is from not being physically fit. But I first noticed it when I was about 26 years old. And, at that time, I was very active and in good shape. So they really don't know.

If slower heart rates go along with being able to tolerate more exertion, then I think faster heart rates go along with being less able to tolerate exertion, especially in the heat. I just know I get a feeling of exhaustion when it is in the 90's. So I have not left the house in days. I have not much to eat in the house. I have not gone out the door even to go outside and check the mail. I know a lot of that is depression. And I know that I am lazy.
