Being ashamed

Im in high school and for a few years i have been dating females and kinda exploring and i find myself slowly turning gay and just finding attraction in women more than men but my parents found out about my girlfriend and really freak out about it and just turn me down making me feel less and ashamed of being who i am and for liking who i like i shut down completely to the point where i just want to cry my eyes out because im not trending like everyone else i like females and i have for a while they make me feel that me liking girls is horrible and that if i countine down this road they will never accept me for who i am im either straight or nothing and this has been borthering for a while because it makes me feel little of myself and makes me think that i shouldnt be open with anybody and i shoould just go back in the closet
