How long can a heart ache before it breaks?

Wow ... a rough couple of days have found me here. Maybe its just because life gets tough sometimes. Currently my family just had a pretty good scare and my great Aunt almost passed away last night. Yes she is a bit older but its never easy to face death weather you are old or young its scary or should I say scary to those of us left behind or who haven't lived enough to die. Right now the word is my Aunt is doing okay for the moment which is a bit of a relief but there is no telling if it will be awhile or just a few moments of time before she passes on. I am young so I have alot of deaths to greif but even the thought of it seems impossible. I know thats the facts of life but the vivid picture of a person lying so weak and you are helpless to save them... its heartbreaking. It really is.
I suppose thats all for now so if I forget to smile sometimes ... its not that I mean to .... I just have alot on my mind .... but incase I don't :D remember I wanted to!
