So glad this is on the right track for you OP. Depending on their assessment, the crisis team should be offering a few avenues such as:
full physical health screen to rule out any organic issues that could be influencing things
review of psychotropic meds by a psychiatrist
either home treatment or day unit to monitor things, this could mean phone calls/ home visits depending on their assessment
youll have their contact details for support and advice if needed
Help her to engage with their input as much as possible. This issue is unlikely to resolve itself overnight so brace yourself and get the support you’ll need from family/ friends/ professionals as needed.
All the best
