llah is the most Merciful, and He's the one who knows what's in our hearts and what our intentions were. He knows what happend, what's happening and what will happen. Putting your trust in Allah first and foremost will help you the most. You have to trust that Allah will give you a way and a chance to practice Islam.
Sis, I kinda know what you're going through, although both of my parents accepted and love the hijab, elhamdulillah!! But when I went to Kosovo and met relatives - I instantly could see some of their negative views on hijab, and I got truly hurt, for what did I not hear them say about me, subhanAllah, May Allah forgive them and guide them inshaAllah.
Sister, how old are you? I do agree with those above, you have to stay strong and still try to talk to your father about it, inshaAllah. But if the situation is that bad, that he would do something to you or your sisters or other relatives, I suggest you to not go over excited with this. After all the hijab should make you feel safe...
But don't loose hope. I asked earlier how old you were, because to be honest, if there is no way to get him into other thoughts,
I'd suggest move from home to an own place or to a good Muslim relative...
But right now, I can only recommend pray, pray and pray! You're in my duas sistah!
