There have been times when I had to go to sleep just believing that God loved me and that I was His child and leave it at that. The problems seemed insurmountable and all that was left to do was to lift my heart to Him and trust Him to make the next day better. How faithful God is, He's never let me down, and I'm thankful that those nights have been few and far between.
I can promise you that there will come a time in your Christian life, that you won't have the answers and you won't see the way God is leading you. You have to keep believing while you trust Him, because the sun will shine again and the answers will come. Learn to trust the One who cares so much more about you than anyone ever could in your lifetime.
