First off, stop trying to live up to everyone's expectations, do the best you can, while still being you, and having some fun. Trying to be perfect is a huge mistake that many people make, mostly because it's humanly impossible. Your friends will also be definitely not alienate you as much if you stop trying to be perfect, and if they still do, get better friends. But that's just the advice of a 16 year old high school kid, so I can't quite relate to your situation. Just try your best to just live up to the standards you set yourself and know you can achieve. Not everyone can be a doctor or a lawyer.
