You are having a really tough time of it, aren't you? I am sorry that she is having so many problems.
I don't know if she is schizophrenic or not. I actually don't know much of anything that would help except to follow your instincts.
is there any way she could register as a special student for a semester, and not need the transcript or be in a degree program but take a few classes? Or take some classes at a community arts center, just something to give her some purpose and creative outlet? Or take prerequisites at a junior college until her transcripts are available? Most jr colleges are a LOT cheaper and transfer to the larger 4 yr univs fairly easily. It cannot hurt to ask.
If you are in Tx, and are talking about UT Austin, I do know a group that she might be interested in and able to work with for a semester or two on an unofficial basis that would get her involved in things. I can pm you IF that is wehre you are. Just PM me and let me know.
