Tim Tebow has a great story. If you haven't heard much about it you need to do some checking. His mom was advised to have an aboriton with him and she chose not to. That will make you think about the importance of life. I was reading a blog on Focus on the family here and was impressed again for what Tim stands for. I would encourage you to read it.
No matter what your story. No matter what struggles or difficulties or the success you've had, God wants to use your story for His glory. So? What's your priority?
