Oh my lands Kerrys, I laughed at your note! I laughed not because I think your situation is humorous but because it so shockingly resembles mine not too long ago.
It used to be that all I could do was live in this kind of venting and agitation. It was all I had to feel better. There are still times when it pops up, but I find myself laughing more at the absurdity of it all rather than feeling horrified.
I found it helpful to read back over my nasty-grams in my journal and use them to find where I can set boundaries for myself. I can't change my geographic location to something far, far, away from my ABF for a while, BUT I can change my boundaries and my focus (to my recovery) to make life far less rant worthy.
These kind of rants remind me of my cats when they have hairballs. They hack 'em up and get as far away as they can from them. I think they have the right idea.
Keep posting.
