What went wrong??

Looking back in perspective, (oh how i hate looking back!!!) I still can't understand how things went so wrong. Did I do something unforgivable? Perhaps. In all truth, I felt that I couldn't be myself. And the worse was that, I was obsessed till it was unhealthy. The thoughts kept me awake at night. But, I thank God that I am finally free. Today's sermon made look back and want to move on. And God in all His mercy and grace is going to give me a chance again, I pray won't screw things up. I guess everything is really premature though, all I hear is a whispered promise from God.
