It's the same in the UK. Rehab is cool, inpatient is not. Inpatient is only for when you can't keep yourself safe or are a risk to others. If you need time to stabilise or adjust to meds or even just a night or two of respite, then there's nowhere. I think a respite facility for mental illness would be an excellent idea, a couple of days where you get looked after and put back on your feet, meds tweaked and care plan adjusted.
