Tremors , involuntary movements. Help?

My case is very complicated.  I was given psychiatric meds  and other meds for vestibular migraine which caused serotonin syndrome and other side effects. I got different diagnosis like anxiety tremors , function neurological disorder , withdrawal effects and akithesia and kindling from meds . My condition worsened because of the constant  trial-and-error . my body is now not tolerating anything,no meds at all ,no supplements ,no vitamins not even paracetamol. I have tremors, involuntary movements and many more symptoms. I can barely walk.. I dont know who to go to anymore  as no doc is ready to help. All neuro/psychiatrist and general physician say they cannot help me as im not tolerating any meds  nor do they admit me . Its been 3 years , im homebound . Is there any neuro which can help ?plz guide  Thank you.
