(I hope this story doesn't make you upset that it wasn't better for you, but maybe it'll give you hope that there are better people out there.)
My parents were actually homophobic for a long time. Well, homophobic isn't the word, they're more just against gay marriage. They don't hate everyone in the LGBTQ community like the "typical" homophobe. After 18 years, I decided to come out to them as bisexual, because it was so hard keeping it locked up inside of me. It was terrifying coming out to them, but very surprisingly, they told me they love me no matter what, and they're accepting of it. They told me as long as I'm happy, they're happy. They also said whoever I choose to marry, they'll attend with the same big smile. It was very comforting to hear all of that, as I thought they would hate me.
Maybe your parents' views will change over time. If not, it's your life, and even though they are your parents, it's your happiness that ultimately matters. They will learn to (at least) accept, if not learn to love, you for who you are eventually.
I genuinely hope things get better for you, and I'm a PM away if you ever need anyone to talk to!
