Grief is uncomfortable but face it we are all predead folks. Moving on is full of mixed feelings. People who we are close to are indelible after they die but they are no longer central to our lives. Some things can't be fixed but we still move forward. In a way grief is chronic.
But so is love, new places and people.
Grief can drive people a little insane but so can other things.
Everyone may know the feeling of being a misfit. That self-doubt might unite some and isolate others. Giving voice to your story is always better than remaining silent. So, good going Dave.
