I want to be erased from existence

Anyone else ever felt this way?

I'm not just talking about suicide. Even if you kill yourself, people will still remember you. I want every trace of my existence to be destroyed. Even if I die, people will still know who I am. I wish I was never born and that no one ever knew who I was.

I want to get my neck cut off by a train but trains have ramming things on the front so that puts me off cuz I'll get bashed not decapitated.
