One thing that helped me was Etsy--I know that sounds funny, but I searched for pet memorials kind of obsessively to give me something to do when I was sad.
I almost bought this bracelet, but decided not to partly because of the price:

(BTW, when I first ever heard about cremation jewelry years ago, I thought the idea was NUTS! But, then it seemed totally different when considering it for a pet. Ha!)
I did get a customized picture frame and a dog tag for my key chain with her name on one side and "Gone from my side but not from my heart" on the other side.
Anyway... those are some of the things that helped me grieve and feel like I was honoring her special place in my heart. It helped.
