prayer?

What happens when we eat and don't pray? Does God need to bless the food anymore than He already has? I think that He has blessed more than we give Him credit for many times. When I say thanks, if I don't really mean it, what am I really saying, "If I don't talk to you God, You might get mad, so I'm trying to appease you." ? Could that be true? How many prayers have i offered up that were so shallow and so full of me?

My deepest prayer ever? "Oh God please Help!"

Thanks!
