Why to believe God?

Some times, I get a feeling that whether God is there not. Because in my family every member are facing alot problems. How much we try to solve them, that much we are drowning in the problems. How much we serve god but God has no kind on us at all. I don t know why God is so angry on my family member and me.

If any one know to solve problems and can any one make me get belief on God.

Please suggest me some advice
