Sounds like how I was feeling all last week. Get some sleep, you might just be tired, or you might need water, dehydration will do that too.

Actually, I guess is because of the light from my computer and in the ambient here. My eyes are too sensible.

My head hurts because of the loud sound i'm watching and listening.

ah, have you got a light on aside from the computer? That can help. But I'd maybe give the screens a rest for a bit, otherwise it'll only get worse.
