Hi, sorry if my English is not that good. English is not my first language. So recently since about at least two months ago I have been having a really fast heart rate. It varies from time to time. I have also been having a lot of anxiety issues for a while now, but I don't think it's related to that. It all started to happen after I took the last dosage of medicine which my doctor prescribed which was for another issue. It hasn't stopped since then. The doctors said it's probably due to anxiety/stress, and it very well maybe. I don't know. I'm just really worried. It's the fear that I could suddenly die that worries me =(
