You have accomplished a lot! I can only admire you for that. I have many illnesses and struggle against weight problems although lately I seem to be losing excess weight. I feel better when I am less heavy. Please know that I am so very, very sorry that you heavily burdened. I hope your brain surgery goes well and leads to the best possible outcome for you. I am due for some surgery too. I face it with trepidation. Ankylosing Spondylitis must be a hard burden to bear. I think you are very heroic.
