Pretty deep stuff

I never intended to have two back-to-back postings about death. 
In fact, I was in the middle of another post when I received the news that my cousin's wife had passed. 
It was expected. 
Due to her suffering, it was probably even welcomed. 
Still, how does one really deal with that? 
I mean, my closest family and friends each hold a very special place in my life.
My husband, my very best friend and truly a life-long partner.  I really can't imagine a single day without him in it.
My kids, all 3 are these perfect blessings. Their imperfections make them perfect. Doesn't make sense, I realize but it does to me.
My siblings, who I learn from and laugh with.  And even though two of them are "new", I don't ever want to be at a stage in life with out you.
My mom, the epitome of selflessness and giving and independence.
My friends. So many of them yet, each one is important to me for different reasons. There is the forever one, the anytime one, the hilarious one, the fun one, the soul-sister, the smart one, the real one, the giving one, and many, many more.  The reality of it is many of my friends are all these wrapped into one. 
I have the best friends and family, I really do. 
Each one serves a purpose.
Each makes me want to be better, do more, worry less, love harder.
A hard pill to swallow is that one day I will have to goodbye to some of them. 
I get tears just thinking about it. 
My life, as I know it, will just never be the same.
Makes you wonder, do you have the same impact on people as they do on you? 
So my question (to end my depressing rambling) is this:  Do you know what purpose you serve in others life? Is it one you are proud of? And, have you told the VIPs in your life just how they make your day better so that one day, when you are telling them good-bye, they'll know why life, as you know it, will never be the same without them?
