I'm still up. I've been having a racing heart for a while and it always bothers me most at night. It's probably anxiety but I can't help worrying something is wrong. I'm already being tested for blood pressure and kidney problems. Tonight I had chest pain that was radiating down my arm so of course I got worried, but there are no buses running so I'm not going to the ER to get it checked. I can't sleep because I'm too worried but since I've gotten out the pain has gone. I hope it doesn't come back.
