What was I thinking?

I think I am usually someone who goes about life and enjoys it. I feel a lot of love, things are usually great and work out for me. Lately I haven't felt that way. I am so thankful for my husband and my kids, but I have been in a funk. Maybe it is my Dad, maybe not. But today a little girl whose blog I read (NOT Rebekah) passed away of cancer. She was only 3 years old. What do I have to complain or be sad about. My children are all healthy. We are able to give them everything they need. I am truly blessed. I feel bad for ever feeling bad. My heart and my prayers go out to little Maggie May's family. God bless you!
