I Want to Be An Actress

I've always wanted to be an actress but my dad has always discouraged me from that. He isn't really a play kind of person which is that's fine but he can at least be happy for me. Last year when I made the play he was like, "Oh great! Now I gotta come RIGHT back to the school and pick you up once again!" That wasn't the reaction I was hoping. I hope he would be happy for me but no he got upset saying he had to pick me up right after he gets off of work. I know he wants to rest but it hurts me that my dad isn't supportive of my acting. My family isn't either.
My aunt was like, "Why do you like doing so many plays? Don't you ever get tired of that?" I though some of my relatives were going to be happy for me." My dad said last year just because I do shows four days doesn't mean he has to be there! He said he doesn't HAVE to be there. That hurt me. I just didn't say anything because I didn't want to argue.
He said I should be focusing on school and graduating this year and not on those dumb plays. My oldest brother supports me and my second brother is okay with it but not a play person either. That's why I tell my oldest brother about them.
I thought families would support what I do. My oldest brother told me not everyone will support everything you do, even family. Dad isn't a play person and me doesn't have to be at every show but he should show support.
My mom supported me before she left the family.
