I understand how you feel. I've felt depressed and lonely too many times to count, especially during 2010-2011. It doesn't help that I have about as much bad luck as Donald Duck/Spiderman and bad things keep happening to me randomly.
Anyways, if you need someone to talk to, my Skype and Steam are zacheatscrackers. I don't really own any of the games you do (except for Doom II, but I hardly play that nowadays since I've beaten it countless times as a kid), but I'm still most certainly available for chit-chatting if you want!
