Eyes gonn deep in skull. Kind of sick.

Hello, im just 27 old, my colour is brown. Im suffering from eye problem since 2 years approx now. The problem is my eyes gone very week, i mean i have no problem with vision only the problem is that my eyes look gonn deep in skull. They look old and also has dark circuls around them, also a little bit of dark circuls mark on nose too.. I take more then 8 hours of sleep every day and sleep by 11 pm usually. Bt i dnt know why this dark circuls are thr. Also i feel sleepy all day, my eyes keep little itching all day all months. I usually tale very mich care of my eyes bt this keeps hapening. 1 yr ago i consulted a doctor who gave me some eye drops but they happened to be ineffective to address the issue. Please let me know what is the proble and how to resolve. I have started wearing eyeglasses to cover my deep gone eyes, because nacked eyes looks very bad and i look like kind of sick.
