Stem Cells for CNS kindling, protracted withdrawal, and medicine damage?

Has anyone had success with stem cell treatments for benzodiazepine or antidepressant induced CNS damage?

Currently I am suffering from protracted withdrawal due to venlafaxine taper. 6 months ago I reduced my dosage just by 7%, but that caused complete physical, neurological and mental collapse. I developed dysautonomia, sexual dysfunction, cognitive impairment and severe worsening of cognitive functions and my underlying ADHD, depression, OCD and anxiety symptoms.

I have a history of approximately five years of SNRI treatment, together with several shorter SSRI trials and unsuccessful medication changes/tapers. Following repeated medication exposures and withdrawals, I developed progressively increased sensitivity to medications, supplements, and other psychoactive substances. After a relatively small reduction in my SNRI dose, my symptoms became significantly worse, where I am now.

The repeated medication changes and withdrawals have resulted in persistent CNS sensitization or a kindling-like phenomenon, involving abnormal neuronal excitability, neuroinflammatory signaling, altered glutamatergic/NMDA signaling, autonomic dysregulation, or impaired neuroplasticity. 

Therefore, I would like to ask if anyone has had a positive experience with stem cell treatment regarding excitotoxicity induced by medication damage/cns kindling. I have only found a couple succesful online comments/mentions of stem cell treatments for protracted withdrawals of benzodiazepines or antidepressants.

Moreover, what type of stem cells should be considered for such a condition (for example MSCs, neural stem cells, MUSE cells, or another cell type).

Can anyone recommend any clinics in Europe?
