I have an extremely uncommon and hopeless situation, what can I do?

People say "oh everyone feels that way", but the difference for me is it's actually true. I can't even go to school because of how bad it is. School drives me closer to a violent outburst, and my own death. I can't focus because it hurts so much, so I don't learn anything. My situation is real, and I'm truly worthless. I don't know what to do.
