When I graduated high school I got a job at five guys. All of my friends were partying and smoking weed the night before my first day, and I wanted to partake but I was worried about a drug testing. So, my friend says, "here, try this. It's synthetic weed" It was K2 and whatever the highest strength was Summit or Elevate or something. Anyways, I took ONE HIT, and I remember lauging and the floor was like waves. Then I remember kinda passing out, and my friend lifting me onto a chair. Suddenly I snap awake, I felt out of my mind. I stand up, and I'm a pretty big guy, at least 6 inches taller than these dudes that gave me the K2 - I go over to them and just unleash a hellfire of cursing and threatening to murder them and their whole families. Asking them what they gave me, feeling like the world was falling apart.
I run into my friend's bathroom and state at myself in the mirror for what feels like forever. Compulsively checking my vitals and eyes and staring at myself. Already feeling intense guilt and regret. I started shaking, so I go back out and everyone is standing around. I'm panicking saying take me to a hospital. Everyone is telling me to calm down. I sit down on the couch because I feel like I'm going to pass out and my vision starts to go. You know, like when you press on your eyes and it gets all pin-holey and eventually just goes black, but I wasn't touching my eyes. I told everyone bye and that I was dying. Then I started to come back and just layed on the couch; completely fucked out of my mind, more due to the panic than anything. I had months of repercussions. I no longer trust my surroundings. I would constantly check to see if I could remember the last 5 minutes, trying to piece together time itself. I felt like I was still high well through my first day (they never drug tested us) and for 6 months felt like I was losing my mind. I would have soul crushing anxiety, and try to sleep in my bed for 40 hours at a time. Not eating, drinking just enough water. It was hell on earth for the next year and I had some really low times.
Time has helped me readjust but I sometimes still compulsively check myself and my memory. I'm a lot less stressed about it and I've moved on over the past 5 years.
Never again.
