One of my students needed to be narcaned.

The kid was so fucked up looking that I called for a nurse. We had to evacuate the classroom while police and EMT came. Apparently the kid was on the floor and not responding. The Narcan didn't work and they needed to take the kid to a hospital. It turns out the kid wasn't on heroin like we all thought. She had mixed marijuana with hardcore SSRIs and is like 90 pounds. She was so barely responsive that they considered putting a breathing tube down her throat at the hospital.

That was the 2nd time I had security alert in my classroom this month.

Earlier a kid came into class and pointed a cellphone at me like a gun. I had him removed and long story short we had a meeting with the parent and the parent straight up said to me "You have PTSD and you shouldn't be a teacher." So this lady basically berated me for like 15 minutes while I just stared at her.
The case worker later came to apologize to me for that whole situation.
