psychology of writing - How to keep going after a failed project?

I was posting my story on another site. After a while it sunk to the bottom. Not a big deal. But soon it seemed like everyone began to ignore it. So I cancelled it because I couldn't keep posting back-to-back and I had nowhere else to share. Nobody tried to talk me out of cancelling it. I'll be honest, it kind of hurt. So I erased more than half of the story I wrote (there was an obvious decline in quality, at least to me) but I can't seem to get my inspiration up enough to continue and I really don't want to scrap this project. So my question is, how do you find the steam to keep going when you know your story partially failed?
