Can I Start the Year Over?

One of my best friends died Friday, Jan 7. His funeral service was yesterday, Jan 11. Accidental death caused by mixing wine and prescription drugs. His partner found him dead on their sofa. Oops, sorry, his "special friend" according to our good old fashioned Southern newspaper obituary. Are you fucking kidding me?
Jon is the one who gave Chloe (the abandoned black pug) to me on Halloween weekend. He is the one who gave me a job when DCI fucked me over two years ago. He dressed me and took me to the hospital when my back left me in gasping agony on the floor. He was my friend.
He was 42 years old.
I don't know how to grieve for him, it's just too enormous.
