I think I may be suffering from this as well. I thought it's normal but I do remember not being able to explain it to my parents when I was younger. I also experience most of the related symptoms:
* tinnitus - less nowadays, but I remember having some problems at night as a child
* depersonalization-derealization - it's occasionally happened for as long as I remember
* fatigue - I thought it was caused by my depression
* speech difficulties - yeah, I thought it's related to the brain fog I get when I'm nervous
* anxiety
* depression
Now, my visual symptoms seem fairly mild, I wouldn't say I've been affected much. But if the other things turn out to be related...

Is anyone doing studies in the UK?
