Loss of sensation in head and body.

It's been 2 years my body used to randomly lose sensation in body( that current-like feeling in our body which makes us feel alive). And after August 2023, this problems grew more. I am not physiologically feeling anything in my head, my throat, my chest and body. Earlier doctor thought it was psychological. He gave me anti depressants for almost a year. But it didn't work. So I have stopped anti depressed almost 8 months ago. My problem still persists. I cannot feel ANYTHING in my head, throat and chest now. I don't even get turned on now. I have lost my libido and I am forgetful. I suddenly forget things and don't remember them back. I have episodes of sudden severe physiological numbness inside my body which even makes it difficult to swallow food. My brain MRI- mild narrowing of cavernous part of bilateral internal carotid artery. Cervical MRI- mild disc bulge at c3 c4 c5 c6 c7 Lower back of my head feels jammed.. Please help me get back sensation in my body, please please please
