I want to die

I woke up a couple days ago and it clicked. I don't know why I have to be here, why my life is so miserable. I'm in sleep mode right now, I honestly want to die. I'm still in high school and my life is already crappy. I lied and I said my sister was harassing me to get a social worker and that was a lie. I don't tell anyone that I want to die a little everyday, I don't tell anyone how I truly feel. I can't. If I do, my parents will have a major fit. I don't know what is going on with my mind, I'm overwhelmed, I'm upset, nothing makes me happy, I hate myself and I don't see the point in living.
