I wanna know what love is

The only thing more difficult than suffering through your own pain, is watching somebody you love struggle through their own. 
The worry.  The sadness.  The helplessness.
Several people I love are fighting separate battles. 
Health issues.  Sorrow.  The break up of a family.
It's painstaking.
How can you be there for them, without being able to "be" there?
And how, when there is finally light shining in your own life, do you keep from sinking under the weight of it all?

Ok so this is more of a "deep" thought than a random one. 
You know what I mean.

"In my life...there's been heartache and pain...I don't know, if I can face it again...can't stop now, I travelled so far...to change this lonely life..."
