Well, for me...you have got to be honest. Speak to god.. tell him your problem. There will be time for everything even for ups and downs. I've been through that, sometimes when i wonder where is god, the next thing I'm in troubles with somethings but I trust in him. Try to take the initiative to make a move, something like you do something for your dad so that he will be happy. Talk to him more, even when you're not praying. Ask for his advices through bibles. God has his purpose in our lives, everyone has different roles. Even when u don't discuss with friends about christianity doesn't mean you are not growing. As we experience him in different ways, our faith grow and trust him more...without knowing...you grow...God Bless You with every drop of water from his words
