I lost my girlfriend, I’ve become obese, I’ve lost contact with my friends because I’ve bevome addicted to my laptop and junk food?

Before I got my laptop a year ago I was 180lbs, but I’m now 320lbs. I stopped talking to my girlfriend as I was too busy concentrating on my laptop and playing games on it, my friends stopped bothering with me after I kept putting off meeting them up, within a year of owning my laptop I have bought over 400 video games and I have proof. I also constantly eat crap like McDonald’s and Pizza Hut, the thing is though I’m happy this way, is it normal that I don’t desire to have friends I can hang out with and a girlfriend I can regularly have sex with?
