I called them for the first time ever back in February of this year due to my first manic episode. I was stoned 24/7 for a month straight after being illegally fired from my job. I was also smoking one of those mystery "mushroom" vapes during this time.
Eventually, I believed that my union had started a massive international social media campaign surrounding my case without telling me. This was exciting and fun at first, until I made a statement insulting Trump and Musk to some of my union siblings. At that point, I started to believe that I was the subject of a gamergate style hate mob and that my life was in danger.
At 3am after at least 2 weeks of very little sleep, I thought I heard noises from my phone that indicated a streamer that hacked me. At this point, I called 911 to report a stalker. Nothing came of the call, but my family knew something was wrong and gave me the help I needed. I'd be happy to share more about what I was believing at the time for those interested; mental health is important folks!
One morning shortly after coming home from a hospital I found a hole in my skin with something of absolutely hideous colour steadily trickling out of it. Spent another week in there and got some stronger stitches.
I think overall it's good to have the experience of calling an ambulance, because now doing that isn't just in the "other" category in my brain, but an actionable option for sudden situations.
