It's great that you are so academically ambitious. I'm sure you will go far.

I think you may be too hyper-focused on geography. Students are accepted to "top" universities like Harvard and MIT from many small towns across the country, in fact, across the world. In fact, it can be a disadvantage to be "another smart kid from a Boston-area prep school" vs having your own unique story.

If you are bored in school, there are amazing and free online classes you can take - even from MIT and Harvard! Check out MITx and edX and even Coursera. Worcester has terrific colleges where perhaps you could audit or even take a class for-credit if you qualify (WPI could be a great fit!) You also might explore AANE (The Asperger/Autism Network) as a source of community and support.

And consider ways you might be able to contribute to your community. Are there issues you care about? Can you make a difference locally? The world is desperately in need of smart, motivated young people like yourself to create change. Top colleges are eager to enroll students who show initiative and leadership. You can do this in Worcester or Holden. There may be ways to enrich your life and find greater connection and balance without a geographic move. Good luck!
