Hi Jason, it sounds like you have a good attitude. That goes a long way in helping one be well. You're also avoiding psychedelics and weed, that is another important step to getting well. You mentioned how your heart rate spikes. I dealt with that for a solid decade. You're practicing meditation. Stick with it! I used to have panic attacks until my doctor sent me to meditation training at a local teaching hospital. It's powerful medicine if you practice. It takes time for the deeper benefits to kick in, but it leveled me out. I practice daily anywhere from 30 to 60 minutes daily, rain or shine. The other thing that helped me was throwing myself into life. Going to school, raising kids, my profession, hobbies, etc. Keep busy, keep focused, keep moving. Perhaps it's worth mentioning, I've never taken prescription medication to treat hppd. I realize medication helps many people in this forum so I'm not knocking it. It just wasn't my path I guess. That, and few doctors had ever heard of this disorder during 80s or 90s.
I'm an old guy who took a truck load of psychedelics when I was a kid. I stopped when I turned 20 after 6 years of heavy use. Life can be wonderful even with this disorder. Don't let it define you. Perhaps that's easy for me to say after all the decades I've had to get used to hppd.
You mentioned "life is forever". It goes by in a flash. Either that or it just seems that way as the decades tick by. To me, it's gone by fast!
I hope what I've written is at least somewhat coherent. Take care.
