Loneliness: Why am I depressed?

I am 77 years old and got an older Dog from an English Dog Rescue...She is going to be 7 years old and such a Darling...She came potty trained, and use to living in the house...I think when we are older it is unfair to get a Puppy that can easily live 10 to 13 years. There are many older Dogs needing to be adopted.

As a youngster, I grew up with a dog in the family. A rescue who was a wonderful, plain, brown dog. Then in junior high, a stray German Shepherd found me and joined the family. Once married we also had dogs until my wife's brain cancer journey made it impossible for us to continue to have a dog for a variety of reasons, chief among them that no aide would agree to work in a house with a dog. So I went 15 years without. A couple years ago my niece convinced me to sign up for a waiting list at a local rescue shelter and I ended up with a several-month-old Labrador puppy. I was incredibly unsure about adding a puppy at almost 70, but it turned out to be marvelous for her and for me. Pets aren't for everyone, but this one did add a nice aspect to renewing me a bit,

Strength, Courage, & Peace
