Hang in there yourself. There's a beautiful song by Crosby, Stills and Nash called "Carry On". I'm gonna listen to it today on my way home from work. Part of the problem I'm having isn't just the cat. In the last 6 years, I've lost both of my older brothers, my dad, AND the cat. I don't think I've adequately grieved any of them. I just kind of quickly go back to work to keep my mind off of it. But I also know that this strategy can blow up as I've just been holding a lot in. The good news is that these are opportune times for "moments of clarity", times when you can see your life as an outsider and plot a new course if necessary. These moments usually involve change and are painful, but by and large, they make up the fabric of most of our lives.

The song I'll be listening to has the following lyrics:

One morning I woke up and I new you were really gone.
A new day, a new way,
And new eyes to see the dawn.
Go your way
I'll go mine and carry on.
The sky is clearing and the night has cried enough
The sun he comes the world so often up.
Rejoice, rejoice, we have no choice but to carry on.
The fortunes of fables are able to sing a song,
Now witness the quickness with which we get along
To sing the blues, you've got to live the dues
And carry on.
Carry on love is coming,
Love is coming to us all.

I wish you all the best with your situation.
