Welcome! I really hope being here is helpful for you. We all try to support each other.

I don't have a child, and I developed Bipolar most likely by my mid-teens but it is hard to know as I had a and case of PTSD. What I do recall is that I was DESPERATE to be helped and really felt I wouldn't survive. I consider myself pretty intelligent so I did manipulate situations to try to get the help I was desperate for. Unfortunately, it was the 90's and no-one (even the professionals - that I wasn't even referred to anyway) had a clue about mental illness even though it was obvious to all at school I was in serious trouble.

I don't know your daughter or situation so this is just an idea shown out there. Maybe she is desperate for help but doesn't know how to ask. This doesn't explain why she would want to be admitted to facilities and not really participate in help. But there must be a good reason she is doing that. I really hope you find some answers and that your daughter's health improves soon.
