Thanks Aeon, timed myself, 3 hours to sort of calm down. I'm not fully calm yet though, I feel like my bones and my blood hurt.
I feel attacked by her, but it's now twisted into she's the victim and I did this to her.

I want to support her but she has these tantrums that drive me nuts. I have bp too, I should know how to be supportive to her. So I'm just trying to take some space until I know the route of least damage to take.

I have not responded to her yet. I just don't know what to say quite yet. I need to be fully calmed down before I talk to her. I did respond to staff, so that part is ok for now.
I could let her know I love her but too upset to talk, or that may just cause more lashing out towards me.
