At one point of time (lasting couple of years) I was in the exact same position, except I do even lesser, I don't even watch movies, listen to music or play video games. I just basically spend loads of time on the computer(like 8,9 hours at a stretch) and read, that's all. Go to bed in the wee hours of the morning and wake up when its really late sometimes, like 4plus in the afternoon, it just makes time that easier to pass. Occasionally I ventured out to buy makeup, but later when I lost all will to even maintain my general appearance, I don't even do that anymore, will not go out nor do anything. My room was in a huge mess (still happens how sometimes) and I just didn't had the energy to tidy it up. And oh, I slept a lot, still do now. It is only in sleep that you forget and the time just flies.
