Based on a true story
You have no idea what your capable of until the situation arrives. For one battered young mother, the choice was simple. Protect her children no matter the cost, from the monster they call Daddy.
Unless you want the cops at your front door, I would change the "I" to a particular character. Like maybe say "a battered woman at the end of her rope". Just a suggestion : )
Or based on your profile, "a battered woman, who was close to killing her husband, marched from Canada to Mexico to raise awareness" . Something like that. It sounds like a very interesting story. I'd put that experience in your log line for sure.
