An Indian introverted teenage girl's confession

Am afraid of the fact that one day I would have to say goodbye to all of my freedom,
Of the day when I will be married and tied to someone for lifetime whom I don't even know,
To leave my lonliless which is my soul companion,
Or maybe I would settle into a deeper lonliness amongst the unknown people.
I don't want to marry, but I cant say this to anyone in our kind of society.
Am not a homosexual who is afraid to reveal her identity,
I am simply one of those introverts who don't want to step in any relationship.
It is difficult for me to open up to anyone, cause most of them don't care
And the ones who care have much more important stuff in their own life.
Sometimes my closed personality suffocates me, but most of the times it is a bliss for me.
Whenever I try to step out from my world, I come back totally destroyed and broken.
People consider me to be arrogant, but how do I explain to them that its just the way I am.
My parents think I don't love them, but how do I tell them that even I don't like being rude to them.
They all think I don't want to listen to their stuff, but believe me even I don't know where I stay lost.
I wish I could run away to some unknown place, and all of them just forgets me.
