How do I become a Young Women?

Hi guys :)

Im a 15 year old Kosovan girl living in London. I've been finding the past couple of months of my life a bit off a struggle emotionally because there's so much going on in my life at the moment that I think everything is going to pass me in a flash.

Im doing my GCSE's at the moment , and I'm expected good grades.

The thing that is bothering me at the moment is becoming a young women. Just to give you an idea of what I look like. I'm 5ft5 (164cm) , dark tanned skin , curly shoulder length hair , pleasent face and slim/average weight (63kg).

I've started my period and have started going through all the physical stages of growing up , but I am still very unsure about everything thats going on.

A few months back I became very inspired by Brooke Shields during her teenage years 13-18, she was an absolute beauty and she had such a presense around her. Basically , I watched most of her movies and her video interviews on Youtube.

Something that I realised in everything I saw was that she was so mature , she had so much poise , and when she walked into a room its like a bright light just shined through.

I know I have the capability of maturing to be just like her. I want to be a young woman that people look up to , I would love to attract some peoples attention in a good way , so people can smile when I walk down the corridor , that sought of thing.

Can you help me ?

Im just looking for some tips. I can't even explain what Im looking for , but if you understood what I've written , maybe you can help me.

Sorry i feel so stupid for asking for peoples help on the internet , but I just want to grow up to be realy delightful and nice and lively .

:)
