[ Lesbian, Gay, Bisexual, and Transgendered ] Open Question : I think I'm bi, and can't tell my mother.?

My mother yells at me constantly because I'm not mainstream and don't like the same **** as she does. She spent all afternoon yelling at me because I'm weird. Last night, I had my two best friends over. Keep in mind I've never been kissed. One of the girls leaned in and kissed me when we were talking and I was about to faint. IT WAS AMAZING! The only thing is, I also like guys. ( I'm female) anyways, i've not got her off of my mind and still can't, and I think I reaaally like her. What do I do? How, or do I tell my mom?
