Haven't got any more reasons

I'm 17f, and the past year has been so hard. I've barely passed any classes and my step-dad has been such a dick. With the election going on, I'm worried about the sake of my future. Work has been terrible. Im currently a senior in high school and I turn 18 soon. Liam Paynes passing also didnt help, i loved his music. I'm thinking of running away but I know i can't because I'll be found easily. I'm really sick of life. I wish I wouldn't wake up honestly. I don't have any actual joy anymore so idk why I keep holding on. It only keeps getting worse. Idk how much longer I'll make it.
