Tashaa,
Pets do wonderful things for us "higher forms of life" don't they? I've read that when people have pets -- it affects their health in a very positive manner, well...there are allergies sometimes. But, they help lower our stress and blood pressure, our mental health is better, too. They are not judgemental little critters and that's purdy nice, too.
I lost my Shelty last year and over the years, you can add, cats, dogs, hampsters, gerbils, parakeets, horses, pet ducks & chickens, rabbits, pot belly pigs and lot of not so warm critters like tropical fish, turtles, even a few special spiders. I am a much richer person for having the experience, knowledge and love for these 'mere' animals. I am glad I met e'm.
I have a 14 y/o Cat in very good health, I would hate to think of her being gone, too.
I think it's good advice, when you're ready..., go save a kitty or puppy at the shelter. I remember when one of my girls, when she was around 12 y/o, had lost another pet...she declared she "...NEVER wanted to have any more pets...cause everyone she loved always seem to die eventually...". It is a real lesson in the reality of death...and life.
Sorry for your loss
