So sorry for your loss SoberForMySon. I have a pet dog that I love dearly and she goes nearly everywhere with me.
I too am starting today as the first of the month in getting sober. You can do this and so can I. Do it for Boo. He would want you to.
I have a two cats buried in my back yard that were also beloved pets. The first lived 18 years and when she died, I was o.k. with it really. She lived a long cat life and I know she was ready to go, so I don't feel all that sad about it. When it is time, it is time.
The other was unexpected, but sometimes pets leave us before their time. If there is a pet heaven, then I know they are o.k.
