I love sleep too. Had a nap this afternoon no problem. But at 11 PM, I lie down and all I get is racing heart.

It kind of started out as health anxiety. I was having health problems and was paranoid I was going to have a seizure and die in my sleep, even though there is absolutely no reason for that to happen. Now I have high blood pressure, so when my heart starts racing like that I get worried I'm going to have a heart attack or stroke, which makes the anxiety even worse.
