I'm so sorry for your family's loss
The only thing that helps is time. I was the biggest mess when my Starr died, I did nothing but cry for weeks. Let it out. Talk about your darling angel. Then you just have to take it day by day and eventually you will be able to think about her and smile instead of cry. When the time is right, another furbaby can really help to ease the pain a bit and help fill that empty hole a little.
Hugs!
