Any other girls lonely hard to find friends

To me being lonely is mostly because I don't to the same things as people my age. I guess being 17 and not acting like a 17 year old makes me boring or not done by girls they're my age that women do do it once they're like in their thirties or forties but when my age don't so it's hard to find friends. It's like I guess I have to make myself different but how do you just do that I wonder
