Okay, 2 thoughts. Not that you asked, but... 1) You're going to crash, and it's okay when you do. This isn't a recovery. I did the same thing, it's part of the plan, usually, but you're not okay the way you think you are, so leave room for the bottom to fall out of this, make sure the right people are there to help, and you're next recovery will be a real one. You don't have to believe me. 2) don't give up on your step-daughter before you've talked to a lawyer. In many states (including mine) there are rights for a "defacto father" that can approximate an adoptive patent, particularly if get biodad isn't on the picture. It depends on the state, but it's worth asking.
A guy gave out a rant and someone reply with the above message. I am guessing it means an "emotional breakdown"?
