Please make comment. Stress issue?

Dear doctors. I hv bn  suffering from continuous dizziness from positional head movements. The doctors(neuro,ortho, ent) i  consulted said it was due to stress issue. They recommended anti vertigo medicine and anti depressant but it seemed to b useless. Mri of brain came normal. X ray of cervical spine was normal . Yes it was true i was under immense stress since 6 months but now i am stress free but am feeling continuous dizziness. During 6 months of immense stress i didnt feel any kind of dizziness but now my question is the dizziness i recently hv felt may b the outcome of 6 months of immense stress or the doctors misdiagnose by telling stress issue?Plz ans doctor. Ur opinions will make my diagnosis easier.
