Hi, 

I’ll try to be brief. I’ve had anxiety most of my life, as well as ADHD, OCD, insomnia, and more recently diagnosed BP2 and BPD. Life is tough for me. To the imminent issue… on the 1st, I was just chilling on the couch watching tv, I felt kinda weird and looked at my watch, and my heart rate was like 110. I was like “wtf”. It stayed there and went fluctuated up to around 125 over the next 30-45 minutes , so I was like “I’ll go lie down”. So I go to lay down, and after a few more minutes, I look, and it’s like 115, laying down. At this point, I go to use the bathroom. And I start feeling really weird, and I look and its 150. At this point, I know I need to go to the ER.
   So I go to the ER, they do all their basic tests, and nothing is wrong as far as they can tell. Send me home. 
  And pretty much, over the last few days, I’ve been having those same random bouts (few minutes to hours) of insanely high heart beat (my resting is 51). Obviously, stress is what’s exacerbating it, but it sometimes feels subconscious. Ex: I was watching the Ohio State Notre Dame game today, and I wasn’t feeling any sort of anxiety or anything of that sort, yet I had really high bpm. Sure, I was anxious, but not superficially (nausea, chest pain, numbness, nothing but that stereotypical anxiety feeling (edgy). For the last three days, I’ve been in a perpetual state like this, with an elevated heart rate, and sometimes the crazy episodes (pulse 110-145), when it has no business being this bad.
    Can someone tell me if they’ve had a similar experience before, and with the end result was of all of it? I can’t go back to the hospital due to the cost (unless it really gets bad), and I don’t have a doctors appointment with my PCP until 9/10. My psychiatrist is going to prescribe me clonazepam, but he’s out of town right now and supposedly can’t until Tuesday :/… 
    Currently I’m feeling extremely well compared to pretty much the last 72 hours, and my pulse is certainly lower than it has been, but it still gets elevated really quick if I do any sort of activity (make food, clean, etc). Like I said though, other than the occasional ache, I really don’t have any “real” symptoms.  
    I I’ve only slept a few hours the last few days, despite having pretty good sleep meds, and overall I just don’t want to die or have something really go wrong, and I want to make sure it’s likely that what I am experiencing is not exceedingly rare?

Thanks for any insight you can share! 

Note- according to my watch, my pulse is pretty normal during the time that I am sleeping. That’s kind of the one thing that’s giving me solace that it might not be super serious. But idk, I’m definitely tweaking 😂🤦‍♂️🙁

(My best educated guess as I had some sort of subconscious triggering event that just fucked me up. Or …possibly something chemically wrong. That notion greatly concerns me
