Please LOVE yourself. A lot of girls here are so scared of what others will think, but you have to start with loving yourself. All of you, (especially the newbies like myself) are amazing people. It's lovely to see such a collection of fine human beings all in one place
Nervousness goes away once you start to love yourself and who you are on the inside. Be whoever you need to be, and love yourself that way, and don't care what anyone else thinks, unless it's fashion advice Remember everyone else isn't you, you are you, and you need to do what you need to do.
I know it sounds crazy but I personally care about everyone on this forum, and it's really sad when the other girls are sad. I just want to give them all a massive hug and have them over for tea, cake and biscuits.
PS: Loving yourself beyond the arrogant will help 10000000% with coming out to people, especially when you convey yourself as a relaxed and chilled human being.
PPS: I know this sounds arrogant as I've only told 15 people so far, but If any of the shy ones needs some tips on the best way come out just PM me and we can talk. Of course I can't give any advice about going out in public because I've not reached that stage myself, but I'm prepping for my first flight very soon! xD
