You can't help her change. Homosexuality isn't a mental illness. I'm not aware of any psychiatric institution that says that being gay is a mental disease.
Some people are born gay, some are born straight. It really doesn't matter Although being gay isn't a mental illness, mental diseases can be caused by parents rejecting their child in any way and for any reason, particularly sexuality. Love your daughter and accept her as the person she is; love is the greatest gift you can give.
Ask her questions about anything you don't understand about her sexuality. Be open and willing to accept what she says as true instead of clinging to preconceptions you have been taught Live and let live, love and let love.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
