I was brought to the ER in a police car because I had a gun. That wasn't fun. Then, I was guarded for several hours and checked by nurses and an on-call psychiatrist. I was transferred to another hospital because all the psych beds were full where I was. I actually preferred that, because my husband worked at the first one. Once in the psych wing, I was examined head to toe for bruising, injuries, etc. That was unexpected and scary, though looking back, I'm not sure why. My stay was tedious and mostly boring, but I got the break from life that I needed, and got on a therapeutic dose of meds for the first time in my life.

I highly recommend walking into an ER on your own terms, not escorted by cops.
