PS, You might find "The Mindful Way Through Depression" by Jon Kabat Zinn and others helpful. It's been a helpful book for me.
The exercises can be integrated into your daily life, rather than having to add an exercise class. It's about relating differently to your life and emotions. You seem like you have a busy life, so maybe you can learn to "slow down" and be present with your busy life, without being harried.
I found the exercises to help in between the recreational activities I have, such as when I'm dealing with responsibilities or a distressing event.
A puppy can really add quality to your life. I think it was a good decision.
One way to be more present with your life is to slow down when you're eating. We turn eating into something else to get thru instead of slowing down to enjoy the joy of food and company. I'm often catching myself eating too fast, and have to prompt myself to slow down.
