Mike, It's a tough road ahead, but it can be navigated. I know, I lost Donna a year ago to cancer as well, and it's still with me. always will be. A good friend told me a week after she died that, "Grief never stops, it just changes." I have found that to be true. This year and two months later I spent a lot of time missing her today. My advice is this, embrace the grief, but don't dwell on it, and don't fight against it.
There is an organization called Griefshare that I attended and it was agreat help. I'm sure if you google it you can find a local group. I highly recommend it.
I love you brother, in spite of the long time since we've seen each other. If you ever need to talk just to unload, call me anytime.
Blessings,
Will
