So last night I developed discomfort i my chest, and shortness of breathe; it made sleep almost impossible, as I had a really harsh heartbeat that felt like it was about to break through my chest, and just as I would almost fall asleep, my heart would jolt and my body would twitch and wake me up. I finally got some rest after i became exhausted in the early hours of the morning. So i woke up and worried, went to see my family doctor, who checked everything... Heart rate, blood pressure, temperature, breathing, heart rythm etc. and came to the conclusion i had a bad cold and gave me some antibiotics and an asthma pump. I double checked and triple checked to make sure it wasn't heart related and she seemed to be confident it was the flu. its been about 9 hours since then, almost time for bed, and i still feel terrible and most likely wont sleep again. Any thoughts? Am i just over-thinking?
