Vertigo or dizziness is a symptom, not a disease. Mental stress can make many forms of vertigo worse, but will not, by itself, produce vertigo.
I am not a Doctor so the information above is strictly FYI. I do feel you should visit your physician as many other things besides anxiety can cause your symptoms. I know how disturbed you must be feeling over all these physical problems so do advocate for yourself. Take care and let us hear from you how you are doing.
