I feel weird since I smoked the other night
Why do you feel weird?
I can't describe what's wrong with me at the moment.
It's perfectly fine to smoke weed as an adult. But if you're feeling like you got too high, you should try laying down and calming down.
I feel like I can't do anything.
You need to calm down and relax. This effect is probably just in your mind and you don't need help.
