What’s going on?

I used to smoke weed in HS, I stopped for a few years and Just last year I smoked weed again for the last time with some friends. Since the very next day and so on I literally haven’t been myself eyes get really heavy “like when I would smoke” I almost feel like I’m still high all the time and can’t come down I know weed doesn’t stay in your system that long so I’m trying to figure out what it could be.. I get really anxious/ paranoid I don’t even like to make eye contact because I always think I look weird all the feelings I’d get when I smoked... how can I fix this ?
