Hello,
I have a big problem with my relationships.

Generally, I have a quite strong personality, I am some kind of confident, extroverted, easy-going and happy. But recently when I meet with someone who has a strong personality, too, I tend to be really quiet, distant and lukewarm. I hate it because people think I am boring when it is really far from true. Even if I do know this "strong" person, I am still very distant and it drives me crazy. I want all of my friends to know the real me.

Is it possible that this kind of people make me uncomfortable even if I do like them? How can I just relax and have fun when I'm with them? I have issues with self-esteem. May it be the cause of my problem? How to fix it?

Thank you very much
