Oh Renae, you are NOT being silly my dear. You are a very loving concerned meowmie.
Like Lisa said, give her time, she WILL be okay. Don't forget, it is traumatizing for these little ones, to go through these surgeries as they do not understand what is happening to them, but they do get over it very fast.
I'm sorry that you have not had a good week and I hope and pray that tomorrow will be a better day for you.

You are such a good meowmie and your precious baby Mina will be loving you again real soon. Hang in there.
