Not afraid to yell

I wouldn't refer to myself as someone that is fearful of many things. If you asked someone that knew me very well, say my brother or my mom, maybe my best friend, to describe me, to give a list of words that would most accurately portray an image of this person, Scott, one word that I'm sure would not be on that list would be fearful. And don't misread what I'm writing...I do fear things. But it isn't a main quality of mine.
And all that is true, with one exception...yelling at God. I'm sure I'm not the only one who feels this way. Sure, there are people out there who openly defy the existence of God, so I'm sure for them to hear me say I fear yelling at God would be just a funny story to tell there friends at the next poetry slam. But for me, I fear the idea of yelling at God. Not even just yelling, but disagreeing or questioning Him about the things in my life or the world at all.
I suppose that I find this to be equated with the idea of being a good son, a good employee, a good student. You don't talk back to your mom or dad, or your boss or teacher. You wouldn't question what they say or do when instructing you. Or at least I wouldn't. So I have always thought, why do it to God?
But what I've realized after reading Psalm 88 and discovering what David Crowder feels about the Psalm in "Praise Habit", is that I'm denying the fullness of a relationship with Him when I accept everything through my mouth but harbor these feelings of why and why not in my heart.
If I don't understand the reason God is doing something, I'm allowed to ask Him why. It doesn't mean He is going to give me an answer I can immediately understand or accept. But being afraid to ask Him why or to let Him know I'm angry with the situation He has placed me in isn't defying His name or belittling Him or making Him angry. It is proving that He exists.
By just accepting everything in my life as "God's plan" but never really allowing myself to be in conversation with Him is denying a true and honest relationship with Him. And it is just PROVING that I believe in Him, that I know He is there and that I know He has a plan that is far greater than I can see, but I need and want Him to show me WHY. Even when He doesn't And when I do that more, I am showing Him my faithfulness. I am saying to Him, I know this and all things come from You, and even if I don't like it and I ask You why, it is me relying on You, and always coming back to You.
