I've tried to explain to my parents that I'm trans before and got told 'No matter what, you'll always be our little girl.' And my dysphoria has been getting worse. I feel like I owe it to them to tell them whats' going on inside my head. And yet I don't think they want to see it. I've been dressing as a boy for the last six months, I cut off my hair and I refuse to wear dresses or skirts, ever. I buy guys clothes. I'm not sure how to tell them, to be honest. I'm not sure how to get them to see it's not a phase. Advice?
You might have a look here: http://emptyclosets.com/forum/gender-identity-expression/156085-i-just-im-kind-scared.html#4 Its a lot of information... I'd say take your time... ask if you have further questions... people will try to support you... you might tell something like its part of you... but the rest stays the same, you will be like your twin brother, and you need this to be happy... some people come out in a letter... I want to come out you might try to build some community on EC, talking to others via wall messages... and you might think about talking to a gender therapist, someone from an lgbt center or a trans helpline, or a counselor from school...
