No info but I want to wish you hatzlacha and bump the thread up for you.
Are you sure residential is your only option? I know it’s sometimes necessary, but there are definitely risks and if you have a good therapist who does evidence based treatment you may be able to avoid that. Have you tried FBT/Maudsley?
Once a patient goes to residential, the relapse rate becomes much higher and full recovery becomes less likely. If her therapist isn’t bringing up FBT, I’d recommend looking into therapists who specialize in that and at least getting an evaluation.
I know it’s confusing and tempting to just send her away, but you can be saving your daughter’s life.
OP, do you know what modality of treatment is her therapist using?
I agree to make sure residential is necessary. She should have more than a therapist at this point. She should have a whole team of local consultants. There are intensive outpatient programs and partial inpatient programs without sending her states away. Has she already done one of those? Every situation is unique so in then end, you know what is best.
Tempting? For real? 
I will daven for her.
This is so tragically hard.
Please H-Shem, let this become a healing journey.
Please tell us if she is with a strong FBT therapist? That is usually indicated first.
Do you feel you have proper guidance? There are so many gaps in the help available to guide parents but keep digging, calling etc.
Please keep us posted. I feel for you.
I agree- having a team is super important.
There are organizations that provide case management and can help you set up a team for your daughter if you need help with that.
OP, did everything work out in the end?
Is Liberty Science Center appropriate for a very frum famil?
Is behavior change natural or something else?
Is this some kind of processing disorder?
