"This is expected from you"- Why?????

I just had a random argument about restrictions put on girls, and the "behavior"expected from them.
My point of argument was why would u have expectations?
why cant they be just who they are..not every one is alike!!?
answer.. society and marriage.
The family name attached to the girl is always taken to consideration..what she wears, how she talks,her behavior?
and the standard dialogue..."Is this how you'll behave in our married household.??"
So am I living my life up to know just to please someone, i never met???
does this even make sense???
I know the world is bad out there.. but being sheltered is suffocating..
I want to get out..

History

Okay..
I was 13.. maybe 12..when it started...
Well a silly shampoo commercial made me realize that people with dandruff have weak hair.. so I had till feeling I did had dandruff and pulled my hair.
After compulsive brushing I came across a fallen hair .. it was different had a different texture, the root.. was different.
and I wanted to find that special type of hair again...
Hence the hair pulling.
It was very late my parents realized that year that i had a bald patch on the back of my head. i was scolded and my pulling habit labelled a 'phase'.
It dint stop.. although the damage was less.. really small patch.. but over the years it has taken the shape of a crescent moon with blobs on it on the well... slightly back of my scalp.

Yes its ugly.. but i needed a wakeup call..The more aware I am about it..coping would be better.

And It happened again

Okay this being my first post I'll start rambling.
Its almost 2.00 clk where I live and Im sitting on my bed , slapping myself ( no.. not because I like it... =_=)
for pulling most of my regrown hair out again.. making me nearly bald. well a good quarter sized patch actually.
I have a severe case of Trichotillomania, bordering on trichotillophagia.(for what it is click here)
Really after finally 3 months of abstinence, checking had paid off... I was happy..
sometimes i wish i could chop my fingers off..
IT just wouldn't stop!
