JJJ, I just throw this out there because you are struggling so hard with Kanga right now.
Therapy is very important to bring the patient back to reality. However, the patient may not truly be able to access therapy without having optimal medications on board. With deeply entrenched psychosis, a patient may need both an older antipsychotic (for example, Haldol, Stelazine, Moban, Trilafon, Mellaril, Navane, Thorazine) PLUS a newer atypical antipsychotic like Abilify (and Kanga is at the highest FDA approved dose of 30 mg). Furthermore, if she truly has a diagnosis of schizoaffective (vs. scyhizophrenia), she may need a mood stabilizer (Depakote, Lithium, Lamictal, Trileptal, Tegretol). Finally, Vyvanse could be destabilizing her and making her psychosis worse. I hope you will talk to the psychiatrist ASAP about optimizing Kanga's medications.
Hang in there. I know today is not going to be easy.
