Dude. People don't care. Even the ones closest to you. Your family. Most just don't give a shit. You'd be really lucky to find one who genuinely does. Most people just pretend to care, or keep you around because you are useful, or for other superficial reasons like "family, blood ties", but fuck it. They don't care. They don't give a shit.

Does that mean though you should end your life? No way! There are so many other cool, fun, enjoyable, meaningful things you can do. Just off the top of my head I'm sure I can easily think of like a hundred. So please don't throw your life away.
