I am so sorry for all the confusing possibilities you have going on. PTSD could certinly be the cause. Is type I diabetes a real possibility. And OMG kidney failure. That would be diabetes related possibly. Are both or those ocurring in your family, you seem mighty young to have that issue. It is good to check for everything. I will be glad and I know you will to when you find out what is going on. Not knowing is difficult.

Thanks for the update, please keep us informed and take care of your self.
