Recently I have been dealing with rapid heartbeats that occur randomly and usually when resting. I have this constant fear that my heart is either going to explode and/or give out from how many times it occurs in a day. 

I’m 30, healthy and weigh about 150 and recently this has been eating away at me. I was diagnosed with anxiety prone to panic attacks but, my mind frequently plays tricks on me and I fall into this feedback loop in my mind that it is a health concern when doctors have told me everything is up to par health wise.

I used marijuana in the past to calm my nerves but, recently if I even get one pull My heart rate spikes to 110-115 bpm. I’ve tried yoga, meditation and nothing is doing the trick right now. 

This constant fear and overthinking takes over my mental process and day to day activities become much more difficult because of my fear of having a heart attack from how intense my heart rate increases. 

I would often run before my anxiety spikes recently but I have never experienced this kind of symptom from anxiety till recently. 

Any recommendations to ease my heart rate? And does anyone still exercise through this symptom? 

The reason I ask is because I tend to get light headed and sometimes I feel like I’m going to faint from relaxing and can’t imagine working out like this. 

I’m so lost and I know I sound ridiculous but, this is my first experience with tachycardia in relation to anxiety and I am just looking for advice.

Thank you all!
