I am sad, really sad

We take life for granted, we think that those who we love will be around forever, it's hard to know that it is not true, life goes on no matter what. I have a huge whole in my stomach and all of a sudden a reallity that I have is hitting me.
My mom is not feelling well, her hep c is deteriorating her really fast. I thank God that she could live many years with it.
Tomorrow I am traveling to Mexico to be with her and my siblings. This is so hard.
