Brave and tough thing to have written. Good man. I hope the process gives you as much back as it gives to the likes of me who have read it. There are aspects where I went "wow" and aspects where I empathised - I was married to a model who was anorexic and then was with someone who had eating disorders - hence the empathy.
I try to remember to celebrate the life as much as mourn the death. Letting go in the appropriate manner is the tough bit because you do not want to seem cold but you equally do not want to lose the opportunity to love again, if you get me!
