Am I not seeing something

So I (25 f) am from South American. I came when I was 6. I always felt like an outsider in America. But I was also too American for my Ecuadorian family. As I’ve grown I have become less and less culturally like the rest of my immediate family and my extended family. This can be due to me moving away from my immediate family bc I felt like a punching bag.

Right now I’m in my home country w/ my mom and am acting really distant bc I don’t really know these people and I’ve changed. We are strangers and I don’t fit in anymore. I smile and listen. I feel as if some people are getting offended. I don’t know there’s anything I can do to make this situation better. Im here for 3 weeks. I don’t hate anyone, I’ve just realized I’m very different from them. (For example they r more extroverted, where as I am more reserved.)
