Having vertigo for a few solid weeks. not my ears (full ent work up done) - not blood sugar or pressure. i have low cortisol and anxiety, related?

Almost certainly not: 3 possibilities come to mind: 1) drug side effect; 2) the ENT missed something; 3) something in the central nervous system. If you self-referred to the ENT, see a general doctor (PCP) for an overall assessment. If you were referred by a doc, go back to him/her. You may need a 2nd ENT or neurologist's opinion. But go through your medlist first.
