First of all you sound like someone I would love to be friends with! I am also extroverted and put myself out there. I believe the right people do value authenticity and vulnerability. How can I tell? Because they open themselves up to me right back. That being said I never know how people really feel about me because I don't care. I love who I am. So I would ask you if its possible you are misinterpreting things because you are self conscious. I would also advice you to keep working on your self esteem. Be the person you love first and foremost. Don't change for other people.
