I get the feeling she's not the right pet for your household. It's no ones fault. She may need a one person home where she's #1 and she may be suffering as much as you are, or more.
I've had many animals from babies that grew up not to be a good fit and I found homes for them where I hope they're happy. Now it's very easy to find homes through craigslist here. The vet is a good place also. They usually have adoption boards. I got our two best pets ever from craigslist who didn't fit in their homes.
