Why don't you pray to God, whenever you feel afraid, worried, depressed. Try confessing him your wrongs and sins and ask Him for forgiveness for the sake of His Son Jesus Christ who gave his life as sacrifice to wash us from them and lead us to Heaven. Study the New Testament Bible to see how Jesus Christ's example and teachings did influence the world from ancient ways of tyranny, violence, slavery to more freedom, peace, love, goodness, gradually improving the western world better than other parents of the world, until people got overfed with wealth and abandoned God and Christ, depending on technology and self-righteous teachings usually copied from Bible and just cutting references to God.
Study the fulfilled prophecies about people of Israel being scattered around the world and then returned to their land. That gentile nations will worship the God of Israel by following a descendant of king David - fulfilled in Jesus Christ. And many others.
