My parents don't Beleive me

So I am pansexual and I tried to tell my parents, who don't believe me. They just keep going on and on about how young I am to know what I am. I try so hard to show it to them and they just say I don't know what I'm talking about. I have 4 friends who are pan,2 friends who are bi, and 3 friends who are gay. They say they have the same problems. I have been pan for two years, and I have dated girls and boys. I tell people that because I don't hide who I am. Whether they like it or not, I am who I am. No one can change my life choices I love who I love, and people can accept that or go cry to there mom about. I have been very upset in the past years about bullying. I will admit I don't exactly handle my anger well. Until then I have and will continue my pride and the more I become honest about this, the happier I am.😄
