hang in there Debbie, I know it's hard. For years I had to have my liver levels checked, and there was no explanation for having a high liver level. I was scared thinking the worse, My aunt had a liver transplant a few years back so I was really thinking all kinds of crazy things, but as in my case my lupus was giving us a wrong test result.
I hope that it is something like this with you. Keep us posted. I will keep you in my prayers. Please try not to think about it so much but I know that is easier said then done.
