what should I do..?

so, my family are all very homophobic, three years ago my mom found out I was bisexual by going through my phone and finding my girlfriends pictures and messages. at this moment she took away all my electronics and told me that what I was feeling was all in my head and that I cannot have emotional or physical attractions to a female like that. I didn't have much of a choice so just as fast as I was forcefully taken out of the "closet" I ran straight back into it. every since then I've been trying to force myself to not be attracted to women. But the older I get the more and more I start to realize that I can't just not be bisexual and I don't know what to do because I can't tell my family how I feel or they would stop talking to me...
