Jeff, I'm genuinely saddened by your loss. I, myself, lost my mother several years ago. It was devastating and, sometimes, it still is. You don't move on, but you learn to live with it. You learn to survive. Just, please, do yourself a favor, and let yourself grieve. Be sad. Be weak. Feel like shit. The mind and body need that emotional release, in times like this. If you need time alone, take it. But, as someone who is very solitary myself, I advise you to take advantage of your loved ones. Be around them. Let them love you.
I'll spare you the bulk of the God talk, since I know you're not a believing man, but I do believe God is with you and your family in your time of grief. You'll be okay, but I'm sure you already know that. You are, in my opinion, one of the finest people in the games industry, and I appreciate you and all you do, despite disagreeing with you, oh, probably 85% of the time. :) God bless, and may 2015 be a year without loss, for you.
