Oh man, this is gutting. My thoughts are with you. At least you got a nice final word, but man, just try to remember to stay positive and let yourself feel whatever comes, whenever it comes. Sometimes it hits quick, sometimes takes a while, but don't think about it, just let it happen.
When my Dad died, it took 2 days before I could feel anything. I was away at the snow and the police came and grabbed me from my apartment but didn't tell me what happened. I got to the station and a family friend told me over the phone. I hung up and went and told my friends, who of course started packing to take me home, but I wouldn't let them, so we stayed the final night, went snowboarding for the full day, and had a great day, then that night, driving back into my street it was like someone was slowly removing my stomach, then seeing my mum as I walked through the door, we just fell to pieces. I'll never forget that.
I think it takes a while to sink in and become reality, and any avenue your brain can find to put that off, it will.
Take care.
