Here come the questions!

ok, so today in church we talked about what it means to really have faith.
this discussion really made me start to question my own.
first question is do I really have the faith I need to carry me through?
second, am I fake? Meaning more or less am I only in this for selfish reasons or do I really
want to know my savior
third, do I really believe this. I mean isn't that what faith is anyway?
Why all these questions, why now. I know this stuff is real because I was there when I committed myself to the Lord a year ago. I have had many spiritual experiences since then, but now I am back in the wilderness again.
This makes me question my faith because am I really able to believe in what I can't see no matter what I'm dealing with in life?
This is some deep stuff and I feel a prompting to figure this out before I go deeper. Can I really handle the depth of all this. God calls us to be fully committed to himself and not wavering in our faith. I felt that in the begining, but now in this wilderness, I feel a numbness and seperation that I am not to pleased with.
How do I get out of this mess and really grasp what God wants me to get from this experience? It is almost like He is purposefully bringing me to the end so all I can do is look up!
But knowing this doesn't help me get anywhere. I am stuck and I need something to get me going again. I really don't want to give up knowing that I've come this far.
