You got a dog, then you always have a friend to go out with. My dog was my secret weapon. She was up for a talk or walk any time of day. There is a reason they are called "mans best friend."
I agree with Gardener, nothing wrong with how you are feeling. Feel it, understand it and deal with it in healthy ways. You can handle it. Just keep getting back up.
Cheers
