Living in the closet becasue of unaccepting family is killing me?

I'm an adult (just in case you were wondering). my mom is a gay-hater. she talks bad about gays all the time (even when were not on the subject). other family members say things like "ewe" most of my silblings are married and etc... I am tierd of being single, and i just want to have someone serious in my life (like a partner), but it hurts to know that they would all criticize me and disown me, and my family would never accept me or my partner and it would be horrible. all the while other siblings spouses are accepted with open arms. I cant even get someone if i am going to hide it from them. they would figure it out eventually espcially if they are living with me. i am way too scared to even face all that sh*T. what should i dO?
