Crushed Under Clutter/Spilling the Speghetti

Ever get to the point in life where you are so overwhelmed with thoughts, emotions, goals, to do's, etc that you almost just can't even function?

I feel that way right now.
In an attempt to share each other's convictions/passions and get more involved in the church my fiance and I committed to WAY to many things.
Though some of them are temporary they are equally if not more draining than the long term service commitments.
We are:
Doing upward pictures,
Serving in AWANA's
taking a life institute class
taking a financial peace class
serving in the choir
and are already currently a part of a small group.
What the heck were we thinking?
On top of that we both have jobs that can be fairly unpredictable, families who are going through difficult times on both sides, and premarital counseling and wedding planning.
Each one of these things requires time, thought, emotion, and spiritual attention. This passed week I have felt convicted ... or rather attacked.
I feel as though every time I take a step I'n being yelled at or beaten up in a spiritual manner. (I know this sounds very charismatic, lion roaring mystical Christan-like but I'm simply referring to spiritual warfare.)
I feel spiritually attacked and reminded of sin, past present and future. I feel pressed and hurt and filthy, alone in the midst of people who love me, and unloveable even around the person who's about to take me as his wife.
This is that ever dreaded place in life where your head tells you what it knows to be true but your heart denies it because of those pesky things humans have called feelings.
This is where we're supposed to tell satan to shove off, stand our ground, and look to Christ. Where the waters rage, the seas roar and hope and light seem to have disappeared although we know better than to trust what we feel.
This is one of those places in life that just... really stinks.
Questions arise that shake the foundation. Am I really saved? How do I know? Why do I feel this way? Am I where I should be? What do I change? Where is God?
Life is so messy, emotions are so fragile, and people are so errant.
What would the world be like without a God who sent a perfect ransom for our sins?
I don't even dare to imagine.

Wisdom

Proverbs says wisdom begins with understanding, but where does understanding begin? James says that if we ask for wisdom we will recieve it.
How do you know if you have it? I guess if you don't know you don't have it, or maybe if you think you're wise you really aren't?
I don't know.
All I know is that I need wisdom and I need direction from God.
What do I do? I ask on a regular basis, seek it in the Bible, but don't feel as though I have any answers yet.
I guess waiting on the Lord is where Patience begins.
