How Do I Know?

I wish there was some easy way to know God's will.  In the deepest part of my heart, I know that God is telling me there is a child waiting for a forever family and we are the family He has planned for that child.  I don't know the age, I don't know the gender, I don't know where....I just know.  But then the other thoughts creep in....thoughts like is this just me wanting this to be true, am I making this all up, am I reading too much into this, is it just wishful thinking, is it selfishness......How do I know if this is really what God is telling me?  It would be so much easier if there was just a clear sign flashing in front of me saying...THIS IS GOD!  I wonder am I feeling this because my faith is not great enough?  I want to have faith that is unshakable and at times I feel like I do have that type of faith but then when the negative thoughts come I wonder just how much faith do I have if I am allowing these questions to cause doubt.  I also can't help but wonder if this is not what God is telling me, then what is it?  What is He calling me to?  I know without a doubt that He is working in my heart and preparing me for something.  I want to do whatever it is He wants me to do.  I want to give my all and follow Him.  I just need to know what and where...and even who.  I am ready to do God's will for me.  I guess this is where the faith comes in though.  I know in my mind that God will work things out in His perfect time and I need to just be still and listen for Him to speak.  I will continue to pray and seek.  I will be ready when God makes it clear. 
I am at a point where I am wondering if I am the problem now.  Am I letting my fear get in the way and that is why I am so uncertain?  Why is this fear in me?  Is this Satan trying to hinder me from doing what God is calling me to do?  Lord, please take this fear away.  Give me the strength to pour my heart out and talk to Randy about this.  My heart is overflowing with a love for an unknown child and it just keeps growing and growing.   God, I see the way you have placed people in my life that would be the perfect support system for me.  Father, please show me and give me the boldness to move if this is your will for me and for our family.  Please give me your peace that passeth all understanding if this is my next step in following you.  I also pray that if I am totally wrong and You are leading me in a completely different direction that I will know that instead.  I want to follow You, I give my all to You....I am Yours Father....Take me and use me according to Your perfect will for my life.  I love you Lord.  Amen.
