That is so sad, and I feel bad about my life, now I feel like a loser feeling bad about my life since I know my immediate family will eventually accept whoever I am. Your family loves you because of what they thought you were, but if they cannot love you as the true version you are then they are in love with an idea. You will eventually accept that their acceptance means nothing, since your own happiness is much more important than their acceptance. If they are capable to say that you should ended your life like a man, then you really do not even deserve them. They do not deserve you at all, and you are too good for them. Believe it, since from my viewpoint you are reaching out for love, and they do not want to receive it. So why bother with it? You can find acceptance other places, but I suppose you feel really alone in the world, but there are people who will love you in this world.
I cannot offer much advice besides that, since I never experience something as low as that yet. But hopefully you can remain strong, and move beyond this point of your life. Just do not end it, since that will mean that you're weaker than them, and be stronger then them. If I were you, I would probably feel impelled to be who I am and reject them all. I would end all contact with them, and if they want my contact then they would have to mutually accept who I am. If not, then they are non-existent to me.
The reason why I am standpoint though, isn't because of my family's acceptance, but of my own acceptance of myself. I do not know who I really am, and where to go with my life. I have a real good idea, but tons of doubt.
