<human>: Condense the text into a few key points

I had a huge crush to a girl i like, we are rather close friends in school and talk about almost anything out of the moon. She is a very cheerful and outgoing girl, she can be strict at times but it's never bad intention and most importantly i wanted to be the one protecting her, she can be hard on the outside but i know she is very soft on her inside.

She participate in lots of activities, her life is very exciting, while i am someone who is socially awkward and spent most of his time infront of computer. She been a very good friend to me, listening to my problem etc, she even gave me advice on how to get a girlfriend(Being more gentleman etc, ironic right). 

I never dared to confess/hint her because i am afraid i am destroying our friendship. I want to change myself to be better, get a life instead of playing games or browsing random stuff. But how should i approach her of my feeling when i am ready? Won't it will be weird that a legit good friend suddenly confessed? I need advice so badly, thanks in advance.
