You will only get support and prayers from me. I have a real problem with people who lie about medical conditions. There is so much real suffering in the world ehn people who are blessed with health "go there" it really sets me off. So for the life of me I cannot understand your W's actions and I am seriously shocked.
But this is about you. You have acted with the utmost honor and you will never get a 2x4 for that. Be good to yourself and take whatever time you need to process things.
As for your W, I am assuming that she is so fogged out that she is totally out of her mind and has not realized what she is doing. I am praying for her as well.
