One thing that can be helpful is to go back and re-read your own thread in its entirety. Pay attention to your own posts and how many times you have acknowledged that W is eating cake. You've been feeding her a lot of cake, none more than the Disney trip where she probably developed diabetes from all the cake you fed her there.
I would also pay special attention to the vets posts, in particular LH's posts on your thread. Just read what LH has been saying.
You have the ability to be a great DBer. First you have to close down your cake bakery.
