growing up!!

If you know me personally you would know that I'm a 20 year old "young lady", but i never act based on my age because i have the life of a 17 year old teenager. i have completely failed to catch up with my age , mentality and attitude and behaviour wise; i don't think that growing up is essential for living a good life, i mean why so serious? actually I'm TERRIFIED of growing up or growing old, it scares me to death and makes me cringe; i hate talking about grown up topics. you may think that i am retarded. I'm not. the reason that i hate growing up so much is because of the responsibilities; i don't like them for they are a heavy burden and i think about them too much, if I'm given a simple task to do i would take too seriously no matter how simple it is i will take it seriously until it's done to perfection and i mean perfection because I'm a true perfectionist, and that serious mood i put myself into deprives me of having fun and being just me.
the other reason why i don't like growing up is the biggest responsibility known to mankind: marriage. now; no matter where you live around this world, girls have so much pressure on them to get married , and yes only girls because a guy if he doesn't get married he is the eternal stud but girls have to get married and have kids and we get that stupid cliche put in our heads since we're young with the dolls and the kitchen  ware toys and when we're older we read all these romantic fairy tales about finding prince charming so were practically brain washed into thinking that it's our destiny to be married and that we are not complete until we are with a man; now don't get me wrong I'm not against that because i know that having another person in your life is an essential at least you won't die alone but it is not the only thing in the world worth accomplishing, especially for us girls, for we need to achieve our own way in life and we have nobody to rely on, we're not in the 50's anymore. another and the last reason i dread the idea of growing up is because i am terrible at interacting with people i don't know like shop vendors and bus ticket collectors and such i just don't feel comfortable and pushing out of the comfort zone is scary; but now i do it on daily bases because i like the rush it gives me. but i still don't want to grow up, is that really hard to do? i don't want to lose my playful spirit and my child like soul.. we only grow up when we stop playing and as for me that will never happen. I here by declare that my young days will never be over.I refuse to grow up.
