It honestly sounds like you had a pretty good "panic attack" my first one happened a few years ago, smoked a fatty with a friend while driving around some beautiful country roads. I usually get a little anxiety when i smoke strong pot, but this was different. My hands started tingling, and all i could think about was death, for about an hour all I did was prepare to die. My body felt somehow calm, yet I was panicking. They are truly scary. I have friends who cannot even be in public places. Another thing, is when you have one, you always think you'll have another during the same situations ie: whenever i drive and smoke I feel the beginning of another. Thankfully I have only had maybe 3 in my entire life, but the following two happened while driving, and smoking..... I found ways to control them tho, I put my hand on my stomach, feel my breathing, think of my dog, tell myself I'm fine really, it's all in my head, and usually, 99% of the time, it goes away. I hope you learn how to control it, and find a way to continue doing what you love,
peace.
ps: Many years ago, when I was going to raves every weekend, and doing X all the time. I had a friend suddenly fall into me, I caught him and brought him to the floor where he went into a full on seizure for a min or two. Scared the shit out of me! He was ok, but never did X again. It was sudden, no epilepsy. was actually coming down from a night of rolling, in my basement before bed. He looked at me and said "whoa I think i'm starting to roll again" and then I will never forget the look he gave me, was so strange, his eyes were fully dilated, totally black and CRAZY looking! then they rolled back, and thats when he fell into me. Very weird, I have heard this from other people too. Not sure what causes it, but I would try and keep it to lower dosages.
