I want all this to be done and never revealed,I am so unhappy.I want to get on blockers and then HRT,but it's too late to stop my puberty most likely.I never wanted all this to happen,and don't want to live with the stigma my whole life and be ostracized by many.

Honey,

Guess what? You are normal; a beautiful young lady waiting to blossom.

Never give in to your fears or doubts. This journey is tough but you are a strong girl and will come through this.

Hugs from an old lady

Big hug! That's why you've got to start taking steps, even if they're tiny. It won't start until you take the first step.

More hugs from another old lady! 

Well,with my family dynamic and all I don't know what the hell to do...

Keep pushing them, find allies, school counselors etc. Your family doctor, school teachers. Be aware of bullies and protect yourself emotionally from them. Be yourself and be proud.

I would have,but my grandma is a staff member at my school.Ill be glad when I graduate in 2 years,I can't take the rejection from my family and class and others.

I know you said you brought up the subject of transgender people and got a negative reaction. Have you tried telling them that you are transgender and need help? That is honestly the best thing you could do, and yes, I know it's scary. But you're already frightened, right?

Hugs, Devlyn

Well,I have no backup plan if they disown me,which is one reason I can't come out,also knowing them they wouldn't do crap

I hope you the best,whatever you do

Thanks.

Well you could ask for a counselor, for emotional reasons ( I wouldn't suggest making something up )...
and pick someone who has, amongst others, gender on their list...
and what you talk with them is confidential... they could help you along the way...

do you happen to be from the uk ?

No,I'm from the US

There is a group especially for transgender youth in the uk...

is there a teacher or school counselor you trust, or could you ask for a counselor at home, and picking someone who has gender on their list ?

If you want to talk to someone in person, you could call at:
glnh dot org/talkline/ (this is the national lgbt youth helpline)
or you could call at the next lgbt center near you and ask for some counseling...

hugs
