As a person who spends 99.99% of his time at home if not at school programming, reading, and watching netflix, what can I do to develop my social skills?

Does anyone else ever get really down when you spend too much time away from your project? I feel myself retracting from society and all I ever want to do is drink coffee and teach myself stuff and work on my game.

It's getting to the point where I don't even want to see my gf and I don't even think about food. I see this happening to me in real time, but I don't want to stop it because I know it's what I need to accel. It's just, damn, it all makes me kind of sad and reflective.
