I've tried a good amount of things, and I think there is something wrong with me

TLDR is basically the title. Tried things and got different effects and am disappointed/worried.

I'm 21, have mental issues and use substances as relief and for fun. I've tried Shrooms, Acid, K, DXM, Molly, Nitrous, benzos, and of course: Weed.

For everything apart from benzos, nitrous and partially weed, I've had such different experiences than those around me doing the exact same thing, and it's getting frustrating and has me wondering, is there something wrong with my brain?

Shrooms normally make me very emotionally unstable, and I only got the classic spiral type visuals at ~3.5g of a high strength strain (can't remember what). Not much/any of the introspection people praise it for.

Acid takes a couple hours longer than anyone else to kick in, and when it does the effects are dissapointing unless I also do a ton of weed. I'm talking no visuals, slight funny feeling, and laughing/smiling a lot. Mainly just euphoria. With weed it's better, but still not very noticeable visuals or appreciation for colour etc.

Molly didn't do anything for me, nothing even slightly noticeable, and I did the exact same dose with my friend in the same way at the same time from the same batch.

My experiences from DXM have mainly just been feeling like I'm drunk, and I know that's expected, but I've seen many people talking about all these crazy feelings, but I've only had the same feeling as having a good amount to drink.

K has been good, it's basically just been time dilation and my brain going slow and not really comprehending things properly, I like my experiences with it (other than that god awful taste). But still, I see people having majorly different feelings (mainly additional stuff on top of that.)

(For all of these, my dosages have been middle to high "common" dosages sourced from psychonauts wiki, and I was not on any medication that would affect any of those at the time I took them, and had tapered off anything that would more than adequately beforehand)

I plan on exploring more things, opioids (being careful with that), gaba stuff, and other psychedelics.

But all this to say: is there something wrong with me? It's dissapointing really, people have life changing experiences and I seem to have things far from that. Maybe I'm just doing stuff wrong and there's some secret to all of these that other people just know that are "common sense"?

I don't know. Any thoughts and opinions would be loved and greatly appreciated.
