Take this heart of stone and make it Yours

So lately I have been convicted about... well my whole life. I mean it's gotten bad. Really bad. My heart has essentially turned to stone. It's been a slow process and very quiet at times. And lately I've just been noticing how heavy a stone heart can be, and how much I would really appriciate some flesh.
Allow me to clarify my metaphor. I am currently living a passionless emotionless lifeless life. I watch TV like I'm getting paid to do it. As a friend pointed out I basically spend my life watching other people live thier lives. I spend time on the internet that is completely useless. I sit around and play mindless computer games for hours. I go to class, do the occasional homework.... oh and you can't forget my 15 minutes I give to God before bed everynight.
And in every level of my media intake I have slowly but surely become desensitized. I don't notice swear words or sexual content anymore. I gun shot barely effects me, and blood is common place.
My heart has also slowly hardend through many wounds. It's full of scar tissue. I get hurt, and it's the most terrible feeling in the world. I have basically decided I will never get hurt again. That takes a lot of wall builing. My heart is super fortified right now. I am not vulerable or available in anyway. Instead of risking hurt, I chose to feel next to nothing.
In no way is my heart postured to recieve from God, yet every night I beg Him for something, anything. I dream, a vision, a word of wisdom. C'mon God, anything! And when I evaluate my day, how can I hear anything from through the defining white noise of my life. How is my life in anyway seeking God?
So I am going to try to make some simple yet life shifting changes, starting with the media. Less TV. I should have the courage to say no TV, but I am not there yet. For one it totally bans me from the lobby, which is the only place I see my friends. For two, I am not that strong yet. Hopefully I will get there. Two, music. I have got to do some serious deleting and some serious adding of good music. Music that points me to Christ.
Third, I need to replace some dead space with actually seeking after Christ. How do I expect to hear his voice when I never stop to listen to what He is saying?
God, overtake my life. For real. Wreck me. Change me. Mold me. Ruin me.
