When I have tried all my life to be good why has this happened to me?

I was sent this video by my brother Vince Covino when I was down into a deep depression. I remember it perfectly as if it were yesterday. I was in the Dallas airport, I was by my self traveling back from Florida, there were people around me sitting next to me and across from me and looking at me as I watched this video on my phone and cried silently as tears ran down my cheeks, much like I'm doing now, as I began to realize there is so many things to be grateful for most of all family both wife and children and also brothers and sisters.
