The first thing I would do would be to call her psychiatrist and get a lithium level done asap. The diarrhea could definitely be linked to the lithium, and lithium toxicity is not something to mess with. Ambien could be behind the other weird symptoms, Oldest had a psychotic episode after mixing Ambien and pain pills once, it was very frightening. Had she taken Ambien before having those episodes?
I think it's time for a sit-down with the psychiatrist to re-evaluate her medications.
Hugs.. and welcome back.
