I could be wrong, but I think what Axelle was saying, is that a big part of fitting in with others depends on being ourselves and
not trying
too hard to fit in.
Trying hard enough (trying in a good way): When we reach for things in ourselves that we have in common with the people around us, and really pay attention to the people around us,sharing those things can bring us closer.
Trying too hard (trying in a bad way): If we try to change ourselves into someone we're not just so that we have something in common, that makes us more strained in our presentation and can make us more, not less awkward. People pick up on that really quick and tend to pull away if we aren't being real.
It's a paradox, but often we fit in best when we stop trying to fit in and just turn our attention away from our selves and towards the other nervous, awkward, trying-too-hard, wonderful people around us.
It can be especially hard if we've struggled for years with gender issues because we may have never felt safe / comfortable / confident being ourselves. We can think we don't fit in when actually we just aren't letting ourselves be all here, right now, and open to the world.

When we finally drop the act, we can find friends we never knew we had. I think that's why I feel so close to people here at Susans - because I can relax and stop worrying if I'm too much for people to handle.
