Pets are a fantastic way to deal with depression. Obviously they won't fix the underlying issues, but they work wonders to elevate your mood.
They do indeed. Unfortunately for me separation from my pet is part of my current depression. My girlfriend and I separated last month (her idea, not mine) and I had to move out. Rented a room (all I can presently afford) and so I'm without my partner of seven years and our puppy, my best friend since he was born three years ago.
I don't know if this separation is temporary or permanent (I hope for the former and fear the latter). I just know how much I miss both of them. And I know my little boy misses me too. She dropped off some mail for me last week, bringing the little guy along and when she rolled down the car window he leapt out the window and just clung to me for the entire time we talked.
