Dear GibsonD,
I am so very sorry that nothing seems to be helping. How utterly heartbreaking. Wish I knew what to say that would help but I can't think of anything. Hopefully others here will see your post and respond with really helpful and practical words. It must be such an ordeal to be going through everything you describe. I can't even imagine. My only hope is that you will find something that really works for you!
Sincerely yours, Yao Wen
