Any Other Options? 7 Years of Suffering

My mom has been severely suffering from brain damage after trying so many psych medications. She's currently in the hospital again due to spiraling out of control, pacing nonstop, extreme anxiety, restlessness, and depression.

7 years ago she was functioning normally with no history of mental illness, alcohol, or drug use. After just one incident of eating a small piece of chocolate with THC she's mentally deteriorated from all the psych meds.

I have tried nearly everything available on and off market to help her. ECT, TMS, psilocybin, ketamine, EMDR, psychotherapy, and more. Doctors have tried every medication out there, and nothing has helped her improve.

I do not want her to suffer anymore. Is there anything else out there?

Update 12/14/23: My mom was hospitalized again and has been there since Thanksgiving day. The caregiver at her care home threatened to quit if my mom was not sent somewhere else due to her persistent pestering behavioral issues. Since my mom does not sleep, she bangs on everyone's doors all throughout the night and defecates in random spots throughout the care home.
