betrayed by the body

Feeling glum today. Got some worrisome news about my mother's health. I'm a wreck about it - I have foolishly come to take her presence in our lives for granted. She's my rock, my guidepost, and a truly loving soul - I assumed she was going to be around forever. Now I am all to keenly aware of how precious little time we really have with those we love. After losing my father 11 1/2 years ago in a matter of weeks- which completely turned my life upside down - I had convinced myself that she would be with us for decades - I mean no god could be so cruel as to take both parents at such a young age, right? I watched my mother cope with the loss of my father with grace, dignity and strength and then find happiness again right at the time that everything in my personal life was falling nicely into place... and things have been going swimmingly for everyone in the family for the past 6 years. Life - or Death rather - has a funny way of rearing its ugly face and biting you in the ass on a semi-regular basis - doesn't it? Of course all these morbid musings are premature - she hasn't gotten a confirmed negative diagnosis - and she seems very optimistic about the whole thing - the MDs said it was likely a benign ovarian cyst - but the paranoid freak in me is already envisioning the worst. I hate that about myself - why can't I just roll with it, hope for the best and be convinced that nothing terrible will happen?
