I (21M) have always had really bad anxiety, but in the past 2 months it has gotten so debilitating. I have been to the ER, urgent care, and doctors convinced that something is wrong with my heart or lungs and that I was dying. I’m on the road to recovery, I started medication a few weeks ago and it has really helped. I have a new cause for concern though:  my heart rate used to be pretty high or I feel like I would have constant palpitations. I’m always checking my pulse multiple times a day to make sure everything is okay. Now, however, I feel like my heart rate is slower than it normally is (even though it’s consecutively in the 60s/70s bpm) and I am just ready to get out of the rut of convincing myself there is something wrong with me. Any tips??
