Continue or not to continue

I started a story that is a little close to my own life at the moment. i really like it but I've hit a point where i don't know if i want to keep writing it. the other problem is that i picked up a old old story from before that's a little out there and i've got a good flow going with so i don't know where to go keep writing this story or go back to the old one? i'm gonna finish the chapter then pop it up on fiction press with endless love and the rest. if anyones interested its called Aquanox games...its a little straight to the point....
