Can I just kill myself?

I can’t take it anymore! All that’s left for me in life is a gun. I’m never going to acomplish anything in life, and even if I do, I won;t even begin to compare with my dear sister’s acomplishments. I don’t see the point in living if all that goes throught my head is depression and confusion. Confusuin to what I am. I know I like other girls, and my friends have accepted that, but am I bi or Lesbian. Bi is one thing, but would they accept lesbian? Not only that, but this is my last year of freedom. I’,m pretty much out at school, which is great, but it won’t be next year. My dad works at the highschool I’m going to go to. Even if I live, I’m never going to be able to hold hands with my girlfriend down the hallway, or speak up in clas if someone says somehting homophobic, because it will all backfire and come to my bigot of a dad. I KNOW he will never accept me, and I can’t take it anymore! I’m only 13, but I feel as if my life is over. I just want to die. My friends are great, yeah, but nobody REALLY understands. I already almost tried suicide once, bbut chikened out. This time I don’t think I’ll hold back. I’M FUCKING DONE.
