Parents. Need Help/Advice

[AlaricXY]

It's not gonna get any easier from here now. But I have to say you have great courage to come out at the age of 16. Bravo.
I am an Asian too, and I can see the difficulty you are facing. Asian families tend to highlight boys as symbol of breadwinner in family and the instrument to ensure offspring to keep the family tree blossoming.
Tradition is good to some extent, but mankind live to adapt and survive, we have been evoluting for decades. If only the society mindset would gave changed as well.
But luckily, your sisters accepted your true nature without mayhem.

I say you need to knock off all bad thoughts of the gays from their minds. Gays are born this way to be attracted to men, we didn't choose, in fact, we don't have a choice, we can't decide.
If they hate the gays, I suggest they should hate themselves because straight people are the one keep making gay babies.

I wish this would be over for you soon. Meanwhile, I suggest you keep this topic understated at your home to avoid heated arguements. Maybe this is a good time for you to seek support from your friends coz you'll be needing some love.
