It's very nice to meet you. But I have to say WOW! You seem to be living through a bad horror story. Everybody is tossing the hot potato around, and the hot potato is you! I'm so sorry to hear about everything that's happened so far, and to know that there is still more ahead. But you do need to keep fighting for your rights. I've never dealt with WC, but it took me nearly two years to get any compensation from SS. When I finally won my case, they did pay me back pay, and they haven't harrassed me since.
What I hate to hear the most is that you are no longer able to do so many of the things which you loved before. I'm in the same boat on that one. You never really realize how much those things mean to you until you can't do them any longer. But you definitely have my wishes that things will get better for you, and your knee will improve. Just hang in there, Nancy. I know that sounds like a cheap thing for me to say, but I promise you that it's based on experience. You will eventually get what should be yours, and your life will get better. Good luck to you!
