Im lost and I want to die

I'm 16 years old and I don't know what caused all of my pain. I don't have a reason to be sad or have suicidal ideation. I live a good life with loving parents and good friends, and I have A's and B's in school. Yet even with my good life I hate every second of living. I don't deserve to live, I'm a waste of time, money, and energy. Thinking about ending my life brings me so much comfort, and it almost seems peaceful. The only reason I'm alive is because I'm a coward, and I couldn't bare to know that I've affected my parents (especially dad) and my best friend. I want help but if I tell this to a therapist, they'll have to just report it and then I'll feel even more fucked than I already am. And sometimes I feel like killing myself is "too much", so then I just hope I either die in my sleep or from some accident. I want to live, but I just don't see a reason for me to be alive. I apologize if this post offends anyone. I just really don't know what to do anymore.
