Thank you for your question - I can only imagine how frustrating this is for you.
My only word of advice might be to try exercise. Sometime doing exercise can help with stress, tension and help your ability to achieve more restful sleep.
If you are experiencing symptoms such as flashing lights, nausea, blurring or vision, changes in sensation and bodily function, it might be worth discussing with your doctor and re-visiting the possibility of a specialist consultation/further imaging.
I hope this helps.
