Prayer again.

I have been struggling lately with prayer. I feel as though my faith is failing me and it hurts. I’m upset that people keep telling the families of murder victims that we’re praying for them but it doesn’t seem to be backed any action. I grew up in church, I believe in God and I prayed as I should, but recently…. I can’t see it. I can’t feel it. I don’t know where to go or what to do. If you have any advice, please don’t shy about it.. I could really use a little help..
