WARNING : EMOTIONAL CONFUSION ALERT

I was sitting through college group tonight totally not focusing on what we were talking about, but on life of late. I had such a hard time feeling like I wasn't failing at life after I chose to drop out of college. I kept asking my self what I was thinking. I'm sure that unless I suddenly developed a passion for some career I won't be going back to study. Therefore according to society in general that makes me a failure. I'll live life working for McDonalds or something. I'm living with my sister and watching her two boys right now. I kept feeling like I wasn't really going anywhere in life and I asked myself what the heck I was doing just about every day. Finally after a lot of talking to God and doing some soul searching I came to have peace that this is just where I am supposed to be right now. Well that peace only lasted like a month.
We talk a lot as christians about having passion for things, God, his work, our relationships, etc. I have to say that until reel recently I haven't felt any kind of joy or passion since I was a kid. It was so great to feel joy again, like I was moving back to being a me that I hadn't been for a long time. This passion thing though is killing me.
I go to church or bible study or college group and I just get so worked up about things. Things like "What is this pastor saying?! Doesn't he realize that this idea that if we are good enough christians that God will bless us with a smooth prosperous life is delusional? What will these people think when they realize that trials are a blessing?" Or this common argument among christians about hymns verses worship music. Hymns are not moldy and in fact have some super theology and great messages. Worship songs are also great. Why do we have to say one is better than the other. We are tearing ourselves apart. Christians are confused and it seems that after a lifetime without passion I am being hit with overwhelming amounts of it every time I do something religious in nature (i.e. church, bible study, college group).
The problem comes in that I don't know what to do with all this emotion. I can't hold on to it and do nothing. I also don't really have anything to pour it into (except a journal and sometimes blogs.. oh lucky you reader! :O) So I get very frustrated. What is it God expects of me? What is it that he is wanting me to do? I simply don't know and in truth it's wearying to even think about.
