Thanks for providing more information. Did the hallucinations, anxiety, and crying happen after you reduced her dose? If so, they are most likely withdrawal symptoms, especially if a large reduction was made.
It might be best to hold her dose for awhile until things stabilize a bit. Once that happens, you'll want to slowly taper off.
We recommend Hyperbolic tapering here at Taper Community - monthly reductions of no more than 10% of the previous month's dose. The reductions will therefore get smaller and smaller as time goes on. The greatest changes in receptor occupancy happen at very low doses, so tapering this way is safer and easier on the brain.
Also, if you go to the Symptoms and Self-Care section of the forum and click on the Guides tab, you'll find lots of helpful information and tips on how to deal with symptoms.
