I think you should print out your points and have them there with you to refer back to each time you feel weak during the process. Remember, don't be pressured just to get it done. Breathe, stay calm, and take a moment when you need to.
I also agree with what Lexie just said. It's nothing but dumb luck that he did not cart your child off while wasted. Remember that, and stress that.
Big hugs to you!
