Hey G, hang on Sweetie. Knowledge is power, so it is best to know what it is about. Just take a deep breath and call. I know it must be so frightening, but, most times it is less horrible than we think.
I know you have been dealt some terrible blows of late, but, it really could be nothing earthshattering.
Either way, it has to be dealt with. So, dig in and I know you will handle it as you have everything else, with strength and dignity.
