What is Up?

Some days I'm just lost for words and lost altogether. I get this roller coaster ride through life and vocational ministry - mostly ministry. I know Satan is attacking me and making me go on this ride... the lows that I feel.... the doubts that I have. I just actually read and commented on a guys blog that I know about this exact thing... "why do people drop out of ministry"... or at least what components contribute to that happening. In my case, I'm trying to figure out if vocational ministry will be the rest of my life or not. And right now I lean towards a big NO. Maybe I just need some guidance or something... direction... to find my actual giftings......
There seems to me that I missed the boat somewhere along the way... the boat of excitement and passion for what we do. Not lack of passion for truth and God, but lack of passion for doing what we do as Youth ministers. I realize that this is revealing of me to say in a public venue like this, but what's the use of hiding it really?
Anyway... God knows the plans He has for me and sometimes I even have a hard time holding on to that.

Any thoughts?
