what drugs not to try?

hey y’all just a question, i was wondering what would be a “no-no” drug for me to stay away from? i smoke weed every once and a while and i want to just try other drugs but im worried how it will affect me. i’m a very paranoid person m, so when i tried weed for the first i was freaking tf out and thought i was dying after 2 cones, so i was wondering what drugs would cause me to just literally relax and feel happy? i want to stay away from hallucinogens, or anything that would make me think i’m dying, so if anyone has any recommendations lmk ! sorry if this was a bit stupid to ask and i knoe everyone is different but i was just curious
