Unknown feeling in eye?

What is the cause of this?

Since I was young, probably 7 or so...I have had a feeling of something on the inside (inner) part of my right eye ball. It was very frequent when I was young and would cause my eye to painfully shut so that I couldn't open it because the feeling would increase. The feeling felt like there was a small ball moving from side to side of my inner eye (the part behind, which you can't see). As I grew older it became less frequent, and quite rare. But, now it is happening less painfully, but often.

I have a cyst on my hypothalamus (benign tumor?)...I think, or else my pituitary...my parent's don't care to tell me much which kind of bothers me...and when I told them of this when I was young (before attempted brain surgery!) they blew it off saying my brain had a problem that dislocated my right eye chasm and I had imaginary feeling or something...As much as I have reminded them of the feeling throughout my life, they disregarded it...
I want to know why now?

I know that the hypothalamus cannot affect the eye directly, especially to have a physical feeling of this. I can't help but think they are *** holes for this...especially because they still don't care to tell me much of my brain, especially because now I am being diagnosed with Lupus (most probably). I am 16 years old, I want to be a neuropsychologist, I am taking college level courses in Psychology...they should know that I can comprehend the matter, maybe even better than them...They think I am not ready to hear it!

Since my parents will not give me information, I would like to seek answers from you, any one who knows what this feeling is?

DONT WORRY!!! when i was younger i had this feeling too! i still get it. if it feels as if there is a little ball jumping in your eye its just because you arent getting enuf sleep! if it starts to really bother you or if it feel as if there is a ball moving all around your eye you should get it checked out
