This was my first time with xanax, bought 6 bars and took 5 throughout the last week and nothing really happened at all, but yesterday I had one 2mg bar after doing bong rips for the first time at some kids house with a couple people. Everything was fine until the xan kicked in and my body felt like it was shutting down, I couldn't breathe or see anything and that's all I remember before I blacked out, my friends told me I was twitching and sweating profusely, eyes rolling to the back of my head, my lips were pale white and my whole body like seized up and I was just tweaking so hard, next thing I remember is my 2 friends holding my hands and walking me around the house and trying to give me food and I could not stand up or process anything that was happening, I really thought I was just sitting in the couch hallucinating the little bits that I remember. The scariest part was I could not breathe at all and I just felt like I was drowning or something and then after some of the people left I snapped out of it and asked everyone what the fuck just happened in the past hour. My friends said they almost called and ambulance and were sure I was gonna die or go into a fucking coma or something, everyone that was there said it was one of the scariest moments or their lives and I barely even remember it. Has anyone had anything similar or know what the fuck happened? I'm a 16 year old girl about like 105 pounds with almost no benzo tolerance so I expected it to be pretty strong but I took 2 bars at once a couple days before and didn't even get high at all though and I smoke weed almost daily and I've mixed them before so I don't get what went wrong especially with just one bar.
