Ahisma,
Welcome to the place no one ever wanted to be. You have found the right place for support and from others who have been through similar situations and can help guide you, or at least share their experiences with you.
This time is the hardest time for you, I know. The first thing is to take care of yourself, which you sound like you've got a level head and are doing so.
Don't hold in the rage....just let it go! I said/yelled/screamed words I'd never used before after all this started. I was a mess! But, it does get better. I won't say it won't get worse before....it's pretty much a roller coaster. Remember, though, in the end, you'll be all right.
Be sure to ask questions...anything you want. We've been there where you are now.
Take good care of yourself and your daughter.
