Even before this birth, I thought you had a penchant for dramatic flair when it came to birthing. But now I see I had it all wrong -- you're only just now coming into your own with your third birth. I hate to think of what might happen if you have another.
No, on a more serious note, I am so happy that you finally got your beautiful birth scene -- reading about it brought tears to my eyes. And I am very sorry that you had to go through 55 hours of labor, two transitions, a lot of family strife and a car chase to get there.
And also, searching for the silver lining in your mom's behavior I came up with this: while your mom was crossing boundaries and in an assaulting way at a spectacularly bad time, at least she was motivated by love and a desire to protect you. Her mama instincts kicked in, and she thought, "Screw decorum, my daughter's in danger." Not excusable, but understandable. She probably felt she had to rescue you, and that saving you from mortal peril was worth threatening your relationship.
