I will try and make this short! I have had headaches, lightheadedness, and mild anxiety my whole life. I wear glasses and all of a sudden over the last 4-6 months I have been experiencing even more symptoms especially inside buildings, driving, and moving quickly. 

I went to see a ophthalmologist and she said I had BVD (vertical heterophoria). She prescribed me prism glasses and I get them next week. 

My question
1. Is it truly BVD that has increased my anxiety, balance, lightheadedness?
2. Is it agoraphobia (anxiety about being in places with out an escape)?
3. Do these glasses actually work and long do they take to work?
4. Can BVD occur very randomly and quickly?

Thank you! I need to get back to my normal self.
