My mom was recently diagnosed as terminal, her heart failure is starting to take its toll. She's almost 90, so I'm somewhat relieved that she has had a good, long life. I'm only 33, and this will be my first real experience with close family loss so needless to say I'm terrified and scared about how I'm going to handle the grief. I'm fortunate enough to have this closure process rather that it being a sudden or unexpected loss.
So, I can't offer much help really, but I can say you're not alone and offer a hug. If you need someone to talk to feel free to pm. I'll do my best to help.
