One foot in front of the other

Yes, my heart is broken and sometimes I don't know which way to turn or even if this will all be worth the pain and the suffering. 
The problem is that I can't know if it all will be worth it. However, I do know that what I have isn't working now, so I will follow my heart. When I train for long runs, and the distance seems too great I always tell myself to keep putting one foot in front of the other. That's what I'm doing now. 
I can't wait to finally live and I can stop looking at my feet.
