The worst family I've ever had

The worst family I've ever had

Hi my home is terrible

My father thinks me as "wolf-girl" and I should be killed
My mother thinks that her daughter (that means me)
should never be happier than her (means my mother)

And the horrible one, is, my little sister

She thinks that she herself is "Swedish princess"
and introduces herself to others

And my little sister thinks that Tsubamemusume should
be killed because Tsubamemusume is an aborigine of Saame people
and resists Swedish Kingdom

And a short story what happend in my house

My mother: Tsubamemusume, change your name
or we will poor people all the time

Mm:Because of you Tsubamemusume because of you
You have "bad name" If you changed your name
then we will be happier

Me(Tsubamemusume): Hmm... Let me see
OK this name will do a great job

Me:I'd like to make my name change like this look at this this is what I...

Mm:Stupid Tsubamemusume how morom you are
You have to use your name for at least 10years
you can't change you name that easily

Question:
Does my mother wants me change my name?
or
Just to want to blame her(Tsubamemusume's) name?

How can I exit this horrible situation?

Are you making plans to move out? I don't understand why they named you a name they don't like.

It's just a name.

How old are you?

Are you a minor?

If you aren't just get the hell away from the idiots.
