So sorry to hear what has happened. I know there's not much we can do and I don't know if you'll ever read this... but should you ever need someone to talk to, you know where you can find us. Good luck.
My Grandma died last year. That didnt make me leave GT though...
But whatever man, if you were going to go anyways I guess it dosent matter whats happened in your personal life. I do wish you the best though, keep on truckin man.
I find myself surrounding myself with people I can talk to in dark times rather than isolating myself. But i guess it's a decision you made... best of luck to ya.
