By nature I'm in introvert so working alone is my preferred situation, but I think I can relate to some of what you are talking about. Give yourself a break, every iteration gives you insight to the problem you are working on, there is no need to get it perfect on the first round. (perfect is the enemy of good). Trick yourself, don't call your code 1.0, label it beta or a prototype for an extended period. Your longer term goal is to get to a release, but your immediate goal is to work on the next point update. Trust yourself, if you think something has a bad code smell note it for later. If you think a UI isn't intuitive, live with it for a little while to figure out exactly what you need to change.
