i'm 18 and i'm too manly to ever be a real woman

my parents are making me see a therapist to try cure my gender dysphoria, but will it work or should i just give up?

i'm tired of being clocky, how do i start effortmaxxing to try to become passing?

>be me, depressed tgirl
>start diy hrt
>fat starts redistributing
>get breast buds
>parents notice and they go through my phone
>they make me stop and they start bloodtesting me
>i love them, but they've forced me to continue living in a monstrous, alien body

how do i deal with this?

is it even possible to pass if you transition after puberty?

all trans women i know who pass transitioned before puberty. is it just not possible after masculinization at 18? should i give up and become a terrorist?
