There are many causes for what you describe, but there is one cause that could be relevant to your situation if I knew:
A. Are you taking a neroleptic drug?
If so, I have an extensive body of research that describes the possibility of what you are referring to and it's causes and cures. If you would like, I could offer you support from my perspective.
