Ask HN: Is there a start-up detox?

This is a throw away account, as I have no intentions of mentioning my start-up. I think I am addicted or way too emotionally attached to my start-up to truly realize I need to stop and move on with life & a new project; stop dreaming that something amazing is going to happen after 4 years.

I have tried many times to move on, but I always see something that I think is telling me I should continue. It's never growth in traffic or user base (it's a consumer social product).

Overall the concept we created was a unique one and now after four years we are seeing a handful of developers and companies spend their time & money executing on the concept, even trying to use our IP. Yet none of the handful that have copied our concept have seen success.

I keep thinking well if others are copying us it has to be worth something and I should continue. I do continue working, but we do not see any growth, as neither do our competitors.

So I ask how did you finally stop working on your start-up and just move on? Did you try and sell it on Ebay or Flippa and or just completely delete it off the web?
