Gender confused

Ever since my first boyfriend and first kiss broke up with me, I've questioned whether I was straight, lesbian, or bisexual My family doesn't realize this. Even if they did, they wouldn't listen or they'd hate me about it. I wonder, could I even be pansexual-a person who doesn't care. My best friend-or ex best friend-said she was bisexual in grade 8. She was able to come out of the closet. But, I can't find the courage to.
Mom, Dad, I'm sorry you had to find out this way.
