dopamine: excited happy, associated with rewards, addiction can give too much and make you seek out the thing youre addicted to

serotonin: calm happy, not enough is depression, too much is bad (though idk how exactly)

I’d hope I do but I haven’t actually checked and I still don’t plan on doing so

(I also just don’t use these words, only read them)

I don’t hence why I try avoid using these words
