When i close my eyes i feel like everything is spinning and like it feels like i have motion sickness even though i sitting still. how do i stop this?

Could be vertigo: When this type of problem happens in a young healthy person it usually is not a serious problem. It can happen from a viral infection that effects your inner ear. That usually goes away by itself. It can also be a condition called BPPV: http://vestibular.org/understanding-vestibular-disorders/types-vestibular-disorders/benign-paroxysmal-positional-vertigo You may want to do tests for a diagnosis.
