Haha just like everyone else here I would say 'be yourself'. I'm a bit weird, I like to dance around and sing songs, and when I do it in front of people who don't know me very well they look at me like I'm a bit mental. That's not a very nice feeling, so I've learned to be a watered down version of me in front of people who don't accept me for who I am... and that's quite a lot of people! Thankfully my boyfriend isn't one of them, and I'm sure that I wouldn't be happy in our relationship if I didn't feel that I could run into the sitting room at any given moment and do a little jig.
It might take a little longer to find someone who truly loves you for who you are, but you'll be much happier in the long run :)
