I for a long time wanted to look just like my mom as far as i can remember, dress like her and stuff boys don't do, as i grew older i found out that i might be transgender, but it is just my family it's kinda old fashion and i have fear that they won't like me for what i feel, how can i tell them, i am fearful of what they might think about me
That's something that you will need to decide, based upon your knowing your family.
Sorry, can't be of more help.
