My first high was bad too, and I've been very open with everyone I've discussed it with about it being terrifyingly awful (among other things, apparently pot makes it difficult for me to get out of the loop when I embark upon a repetitive behavior of some kind, possibly because I am neurodivergent and have repetition issues anyway. I would start scratching my leg, for example, and it would require every shred of my willpower to stop before I took off all of my skin -- I have scars from that evening). I've come in for a little bit of friendly mocking, but no more than I deliberately invite on a regular basis (that is, not above the friendly mocking baseline for my social circle), and have received several more casual offers of pot, but no pressure to try it again.

I can't speak for your friends, and there are a lot of factors here, like age -- if you and your social circle are of the age at which sharing drugs is a matter of social initiation, which I am not, this may be different for you -- but potheads are mostly pretty mellow, and the average regular user has had a bad high of their own at some point. I would be surprised if this came back to bite you socially. If it does, explain that you were having a panic attack. Obviously, I'm sympathetic because I've had a bad high myself, but I was moved by your description.
