She called the police. Or an "ambulance" as she says, but the police showed up.

I was discharged from hospital literally an hour before just asking her not to talk to me because I'm stressed, unless it's an emergency please let me be. I was in no danger to myself, I was literally just watching a documentary. 

This is why people don't reach out, and why I certainly won't again. I don't want to bother with the police, I don't want to go back to hospital when I just got discharged. I don't want to go through the motions of people being abrasive and harsh when I need softness and warmth.
