Don't be sorry at all bro. I'm sorry to hear that, you know we're all here for you.
Take some time off, if you need to get it game, put voice_enable 0 in console and pwn some faces.

I know how it feels to lose a grandmother that's close to you. I feel your pain, and my sympathies go out to you and your family.

Hopefully these boobies make you feel a little better.
