I am a former mental health advocate. I don't know the whole picture but if she needs a full time care taker I'm going to guess she is unemployed and may qualify for medicaid. If she does qualify and can't apply with out assistance the best way to go may be to trying to get her enrolled in some type of mental health case management. I know she currently does not have a diagnosis but by applying for services or even calling case management agencies you may be able to get advice or even get her case management to get the help she needs... Medicaid is your best bet to go. If you work their may be a way to put her under your work insurance as well. Good luck on this and if you need some tips please feel free to e-mail me through this web site. I'm new to this site so... I think you can e-mail on here.
