Bad experience... feeling off days after & cant stop overthinking

Hey yall, so since my situation is very detailed ima make a short version and a long version of the story, so here it goes.

Short:
A little over a week ago (wednesday, 06/26) I smoked with a couple of friends. Im an ocasional smoker meaning i only do it very few times a month (1-3 max) or not at all. That night, i had a “bad trip” in which i think i greened out basically, which caused me to feel scared and then led to me having a panic/anxiety attack that lasted a whole hour, not sure which of the two but yeah. Its been a bit over a week and i still feel weird, my head feels foggy at times and i cant stop overthinking things. Could it be just my mind reacting to trauma from the event? Do i just have anxiety from what happened and its causing me to overthink? If this has happened to anyone, id appreciate some help . This whole situation has been driving me crazy


Long:
So basically everything i said before, but with more detail.

I’m not a frequent smoker, only on some occasions, and this time i did more than what i had been used to. Here are things ive felt that ive written down:

-When we began to walk back from the smoke spot, i began to feel numb and lightheaded, as if i were about to fall (similar to the feeling of exhaustion from running laps, and in need of water)

-When i finally sat down in my friends car, it only took a few seconds until i started feeling off

-I told my friends something was wrong

-i started feeling my heart rate escalate intensely, as if i were having a heart attack and was going to do die, but my friends felt my chest and told me it seemed perfectly normal

-They got me some food and water and i calmed down a bit

-I went home with one of my friends and went to sleep

-The next morning i woke up calmed down, but i felt “off” and out-of-it, its kinda hard to explain

-I researched what i was feeling and the most frequent answers that popped up were: hangover, cannabis induced panic/anxiety attack, derealization/depersonalization

-i felt like that for days, but it wore down very slowly

-there are points where i feel about 90-95% better and almost back to normal, but then it just comes back again. And it just cycles everyday. I think its because the thoughts linger in my mind and i become paranoid and overthink a lottt.

-I also found out that i could be experiencing symptoms of trauma from a panic/anxiety attack.

-Everything about my body feels fine except my head and my mind. When i start to overthink again, my head feels pressured and a bit heavier, sort of like a headache but not really and i start feeling weird again, and it drives me crazy!
