I feel so stupid and ungrateful

I feel so bad, I feel so bad for all the people that got them homes and things and pets destroyed. I have so much to my greatful for, why am I not doing what i need to keep myself healthy. I can not bare the sadness that I see on TV. I should be go greatful, and yet I treat myself like crap, its like i am not even thankful for all God has given me. I don't know what to do, I tell myself just to do what i know is right, eat good, but it feels like an impossible task. I feel like i don't deserve Gods help, because I am doing this to myself. Sad and scared
