Some online friends called 911 on my son when he was just a few weeks shy of 18 and he was placed on a psych hold for a week for self-harming thoughts.
Don’t get me wrong, I am very grateful they saw signs he’d managed to hide from us, but since the paperwork took a few weeks to process, he not only had to deal with his mental health issues, but also got an 18th birthday present of a $20,000 bill for inpatient services under his name. That definitely didn’t help his mental state at all, and it took years to sort it out.
Later, he told me all he learned from the whole experience was to never tell anyone what he really thinks. As a mom, that scares the shit out of me.
