I can relate with the fitting in part, though my situation is the complete opposite. I am a self-taught developer that skipped college and I have been a professional software engineer since 18, I am now 21 and have been programming for at least 8 years. At the company I am now working for as a senior engineer I am the youngest here by a large margin. I am the most experienced and youngest and it has caused a bit of hostility towards me. I can understand why though but luckily it has died down since I have been here a few months.
