I kinda of had an experience like that once or twice, but I was about a month or two into smoking (been about 8 years ago now, god I'm getting old!!!). My legs felt wobbly and I felt like my breathing was real screwed up. Took me a while to realize it was all just in my head (and when I say a while I mean a couple hours). It was the two times where, at the time I hadn't smoked nearly as much as I ever had before (up to that point) and I was by myself, which I think was most of it. I've had some friends experience similar things, but none of them the emotional roller coaster you describe though. Mostly they were physical effects. My advice would be next to to 1. Don't be around someone who doesn't smoke next time, people that aren't high seem to be more paranoid to me than people that aren't. 2. Definetly don't smoke out of foil (it is poison). 3. Just remind yourself of the good things about being high calm yourself down and you'll forget you were ever upset, keep it up beat and you should be fine. If it happens next time you smoke, I don't think I would smoke anymore. It could be a sign of a deep rooted emotional or mental problem. Hope this helped
