I know it's hard right now. Everything you see or hear reminds you of him. In time, though, those same things will evoke sweet memories instead of pain. I always liked the following poem. Perhaps if you can see Mike's passing this way, it will help:
Do not stand at my grave and weep;
I am not there. I do not sleep.
I am a thousand winds that blow.
I am the diamond glints on snow.
I am the sunlight on ripened grain.
I am the gentle autumn rain.
When you awaken in the morning's hush,
I am the swift uplifting rush
Of quiet birds in circled flight.
I am the soft stars that shine at night.
Do not stand at my grave and cry;
I am not there. I did not die.
