sorry to hear about what you are struggling with.. it isn't easy.
It sounds like you are doing a good job in responding to her and it is important to keep strong and focused on what you have told her.
An option could always be to ignore the texts and calls for a day to help you stay stay centered and not get caught up in her frenzy.
If she is serious about cleaning up she will do the work needed to get it done. Refusing the ER could be a sign of not being done yet.
There are treatment programs out there that don't cost. You don't have to keep paying for rehab.
My thoughts are with you and your daughter today.
