I can't commit!

I am so frustrated at myself. I should have gotten up this morning to go running, to train for the marathon that I am "thinking" about doing in September. When I decided to run the half marathon sometime last March it was easy for me to stay on schedule; I never missed a day. But this time, I am having a really hard time comitting. I suppose there is a part of me that thinks I am pushing it too soon or that I don't have what it takes to run that far. I need to keep praying about what to do but right now I am just frustrated. :(

Thanks for listening.
