Per your description it looks more like physical rather than stress related - however more comprehensive history and examination might be helpful. Some of my thoughts - 1. If the giddiness starts when you get up in the morning and you feel better when you lie down - it could be orthostatic hypotention (blood pressure drops when you stand up) - could be result of medications/underlying medical condition/dehydration, etc OR benign positional vertigo (feel dizzy in certain positions) - no obvious physical cause but not related to stress and gets better with certain exercises. 2. If you have other symptoms of anxiety - such as episodic excessive anxiety, nervousness, fear, increased heart rate, difficulty breathing OR persistent worry - your dizziness may relate to stress. In any case you should get a second opinion to rule out physical causes for persistent dizziness. Hope this is helpful.
