How can I best manage my symptoms of headaches, dizziness and light sensitivity?

Thank you for sharing your concerns. Sounds like you are a young lady with "mild depression" who gets frequent headaches. Most people can feel like they are at their wit's ends when dealing with such problems. There seem to be infinite treatment and test options. It can be hard to find a doctor who will give you an opinion on what should the next step be. But it does sound like your GP cares a lot about you and does give you sound advice. Perhaps you can go back and check with your GP again.

There are many possible causes of feeling faint and dizzy so it will be good to seek the help of a medical doctor for a proper medical evaluation. Blood tests would also be required. Reasons why you are feeling faint or dizzy Here is a list of some of the common conditions that I have encountered in my years of experience as a doctor: Dehydration. When a person does not drink enough fluids, the blood pressure goes down. As a result, there is a lack of oxygen supply to the brain and a person would feel dizzy.
