Addicted To Computer Games, Lost Senses, Fell Down, Lip Bleeding, Bruise On Elbow. Reason?

Hi doctor, I ve been playing a lot of computer games recently. For the last three days I have been playing games from 4 pm to 7 am. I slept at 7 and woke up at around 4 again. I only at dinner at 6 and continued playing again. I drank probably two cups of water per day. Then I noticed my body losing its senses. Just last night, I woke up at 7 and walked to the living. I was still very sleepy and wanted to lie down on the couch. But, as I almost got to the couch, I fell and I don t even remember how I fell. I dont remember how hard i fell or anything. My parents rushed over to see what happened and at that point was when I realized I had just fallen down. I didn t feel any pain at all. Then my mom noticed that my lip was bleeding . And eventually I felt a bruise on my elbow as I place it down on a table. My question is why did I lose my sense of direction? Like I don t feel hunger, or thirst. I don t feel the need to urinate, but when I went anyways I had A LOT of urine because I haven t went to the bathroom for almost twelve hours. I don t know why I keep playing this stupid game. I m an ap student but for the last few weeks I didn t even bothered with my homework and just played games. My grade dropped dramatically. I think I might have depression or something. I don t have the motivation to do anything. Sorry for jumping around everywhere. Thank you, Tony
