Thanks again for your replies and insight. I will definitely be discussing this with her psychiatrist. She has signed the waiver. I don’t know what the school insurance plan is yet, as she has just turned in her application. Approval seems likely, but @compmom’s comments make me wonder if the school could use her mental health history as a reason to deny her. (They did require her to get approval from her therapist, so maybe that will be sufficient to fill their mental health requirements.) I will also look into the Square Mouth insurance.
Her meds are now generic, so if insurance won’t pay for a six month supply, we can cover that. Her psych doesn’t think there will be a problem in any case, as he has worked with study abroad kids before.
I do hope this plan works for her, but not at the cost of the progress she has made.
