I was in a very similar situation...

So I went and got a job. A few months in and I'm ready to get back to work by myself. But I think I'll stay put for a bit. It's nice having other people around during the day and I think I'm actually getting more done nights/weekends on (now) side projects than I was the last few months on my own. I'm certainly managing my time better.

I defiantly feel your angst though. I have been there and it was not fun and was killing my productivity.
