A certain kitty came into your life for a reason. Whether she gets to stay or needs to return to a previous home isn't what matters. She has shown you that having a special kitty in your life is something you need. Both quilting and a little dog are what has gotten me through some truely hard years recently. Some days I would have given up, but my little rescue dog makes me go on.
Keep thinking forward. When a rough period hits, (as it does for all people) just hold your dear kitty. And if she leaves you, go immediately and get a new kitty-there are plenty that need homes! Good luck and praying your health improves and each day is happy for you.
