last summer I tried weed for the first time at a concert. I am on anti-depressants and have relatively low blood pressure. Almost instantly I had collapsed to sit down. Soon after I couldn't move my body or talk. I couldn't sit up without someone supporting me, and if I moved even an inch I felt like I was being thrown. The concert was in slow motion, and the effect went on for hours. People would ask me questions and I'd answer screaming in my head, but I couldn't speak. Everyone was laughing and saying I was just crazy ripped, but I'd never heard of people being that bad or scared. I've searched the whole internet, but I can't find an explanation. Help me please!
