i got that before when i was still a rookie blazer and i smoked some really really good bud when i was used to smoking cheap bud. so anyways i was feeling like you and i was thinking about how much of a fuck up i am and shit like that and i was hearing shit and thinking i was gonna die and my life was flashing in front of my eyes (pretty much a really bad experience). but then my friend told me to chill and he was telling me stuff and chilling me out. then the next day i had the same stuff and i controled it better and had a good time.

next time you smoke just chill and relax, let the weed do its thing.
