Skeye always try to emember that with each new sunrise there brings new hope.
Many many new treatments,surgeries,prostetics,vaccines,and even cures were born overnight! None of us knows when one of those bright new young med students up and coming will be our savior.
Keep searching and researching and anything you find that is in trial or being tested even in lab for the moment can be a virtual answer for any one of us.
We can never allow ourselves to lose hope for then we tend to stop searching and pushing for the answers in treatments.
I have took lots of things I have found via the internet and research to the table for me and my Docs to try,some have helped and some have failed but none of them have left me worse for the ware and thank goodness I have a Doc willing to allow me to do these things. He has been my answer to prayers for years in his actually instigating me and pushing me to be hands on with my own treatment in trial and error some times.
I truly believe he is the reason I do as well as I do and I know he is the reason behind my always pushing each one to search out someone willing to allow them to be a part of their own process of treatment options.
I am sorry you have been let down again but keep trying to hang on to the faith that this may be your day,your answer,your hope in finding what will work.
