Don, I am just so, so sorry for your pain. I have no doubt at all that losing Elvis feels completely devastating.
I have just one family member remaining and have been very isolated since moving across the country in 2014 and enduring a series of adversities that haven't allowed me to rebuild any real kind of life and connections. I only say that to share that I understand losing a beloved pet that meant everything to you--and how very very profound your loss is. It is extremely hard to absorb the shock and adjust to life afterward. I do know it gets better because I lost a 17 y.o. dog in 2006. It helps me with my current loss to remind myself that I have lived through something like this before, and that it does eventually get better. But it takes real time. Thinking of you today and wishing you comfort and peace. And hoping things start to get easier for you.
