Manchester, I'm sorry you are having all of these problems. My UC was diagnosed 14 years before my surgeries and had it years before it was finally diagnosed. I have PTSD, depression and anxiety as well as fibromyalgia and a few other autoimmune problems.
I know it's hard for people to understand why we have PTSD and such as they are all hidden disabilities, until we loose or gain too much weight. I found out in counseling that this was not the first trauma in my life and am having to deal with the abuse I suffered as a child through adulthood by my mother. There are other trauma's too and all of the surgeries and aftermath pushed me over the trauma edge.
I'm so glad you now have an income so that you can concentrate of getting better. I had my required physical exam today and have my psych evaluation Thursday. Both paid for by the government. Even though they had medical records from 5 doctors and my therapist. Hopefully I will soon be approved - but if not will appeal.
