Hi, I also suffer the same thing. I didn't make a post yet about my super severe anxiety and panic attacks before (yr.1999-2003) and I get well after the yr.2003. My heart rate before is very high same as yours even higher like 120-130 bpm. 1st what I quickly did when the time I'm in a recovery mode is "PROPER & HEALTHY DIET" I eat vegetables and fruits mostly and meat sparingly, the 2nd best thing I did is "EXERCISE" at start, I just walk (with companion from my very kind uncle) like say 30 steps and I return home then vomit, that's how weak I am.. but to make the story short I became strong and strong each day until I do weights (barbells)... until now... then until I can do joggings and boxing (punching bag) my very good Cardiologist, Psychiatrist and Integrative / homeopathy Doctors helps me a lot, they help me bec. I also did my best to help myself up. That's it
Don't lose hope. I've tried almost everything before, I combined conventional and natural medicine and they worked great!
So, have a healthy lifestyle: HEALTHY DIET & EXERCISE
Exercise will make your Heart and overall Organs Strong and healthy, also it will detoxify you, some toxins in our body will release through sweats. There are lots of benefits we can get from exercise. From my 120bpsm before it became 68bpm when I became strong already. Our heart is a muscle, so it needs to be strenghten through Exercise, if you will not exercise your body this muscle (the heart) will go weak overtime. It's best if you work with this with your doctor consent.
Hopefully, I'll post my full story here in this website soon
All the best!
hope thid helps
