I cannot explain your confusion but I can give you some examples of how to properly use "should" and "have to". What you "should" do is what you believe is the right thing to do. You are not forced to do what you "should" do. What you "have to" do is something that you are forced to do. For example, you should eat vegetables and fruit, but you have to eat something.
