This is one of the saddest things to go through- I’m sorry for your loss. Just went through the same a couple weeks ago, and I gotta say, being proactive about the grieving process was a huge help. Everyone grieves differently, but I would recommend prioritizing the process- set aside time for yourself and your feelings every day.

One of best things my partner and I did was make bracelets out of beads that matched the fur and eye colors of our late cat, and it made it feel like her essence was still around with us. Highly recommend.
