My mind and body feel as if i'm very slow and numb........?

Dude, I know EXACTLY what you're talking about.I'm a fifteen year old girl and I just recently went through this.. At first, tons of people told me that it was probably laced weed. So, if that's the case exercise a lot. The THC stores in your fat cells. And by sweating it gets it out quicker. Also, lay off the sugar. Drink a TON of water. And this seems impossible, cause it was for me, but, try not to think about it. I know, sounds impossible, but try. Watch movies. SLEEP. Distract yourself. But, if it doesn't go away in a few weeks/months see a doctor. That's what I'm doing tomorrow. And I only smoked like 5 times before in my life..but that last time.. I was ****** up. and that was almost three months ago. The feeling isn't as bad anymore, but it's here enough to tick me off. I think it might be a little disorder called Depersonalization. But, don't worry, this goes away eventually. I really hope you feel better soon. I've been there, and it's not somewhere I'd wish for anyone to be. I'm sorry.
