2 months today and my heart still aches

How do people move forward? Yesterday, as I finally mustered up the courage to go through Orion's things and separating things to donate, I came across his favorite comb still full of his hair. It was a flea comb (even though he never had fleas) but he loved the way it felt as I combed him. Greyhounds are bony, all his other brushes were never as pleasant for him as this one. All those little hairs on the comb just destroyed me. I spent the whole day crying, missing him. Is it weird that after cleaning the comb, I put that tuft of fur in a little box? I just miss him so much, I want to hold onto as much of him as I can.
