Hi, my name is Sarah. I am 15 years old. Sometimes, typically in the morning, my vision becomes blurry to the point where it is black and I cannot see. This has been happening for as long as I can remember. Along with the blurry vision, I get this weird sensation in my head... It is not exactly dizzyness, but usually I have to (if I'm standing up) put my head down so my chin is on my chest or lean on something. It happens about once or twice a month, but it varies. For example, I think it happened about four times in one month but it hasn't happened for a long time, so it is very unpredictable. I tend to get low blood sugars in the morning if I skip breakfast/wait too long to eat breakfast, so I don't know if that ties into this. I have told my family only a few times, because I used to think it was normal, but they are a little concerned, so I do not think it is normal. Please let me know soon, I am really curious why this is happening.
