i dont understand why weed makes everyone else "chill"

(17F) I feel like I'm so alone in this and it's making me silently—slowly but surely—lose my fcking mind :) when smoking weed, most people experience a pleasant euphoria and a sense of relaxation. THAT IS NEVER THE CASE FOR ME. is it because of my bad anxiety? just the chemicals in my brain? or is it my mental state? maybe it's just the weed? I'm not sure but it's driving me insane because no one knows what I'm talking about. This is more than just the "i smoked too much and I'm paranoid now". I will take one hit and will have trouble breathing and be physically shaking because I'm so anxious. Like the static in my ear becomes sharper and I can feel the itch on my elbow bubbling under my skin. And my god, my social anxiety goes through the roof. I will say one thing and then spiral to the point that I never want to speak again all within 5 seconds in my mind. Even with people I'm most comfortable with, I still feel like the world is going to end. I feel like I want to crawl into a hole, embrace myself, and hide forever when I'm high + have trouble making any thought come "full circle". What confuses me is that I've done marijuana in literally every form (and only on occasion) but EVERY TIME, it still feels like I'm high again for the first time. I have been getting better at opting out w/my friends but sometimes I think I can handle it and then...yup, my mind begins to consume itself and I wonder to myself why I thought it'd be different this time...ANYWAY LMAO...anyone have any possible explanations or advice?

*yes, i think i’m just gonna stop but i feel embarrassed about this... & i'm on 40 mg of fluoxetine if that's relevant

edit (8/27): i took the time to smoke alone + in a familiar environment and i feel like i’ve “trained” myself to be better at smoking w other people…i wanna say it’s a better experience now but i think i need to accept that i’m chronically anxious— how i feel high is in total relation to how anxious i’m feeling that day/in that situation
