Sometimes I really want to give up and never look back

It feels like a waste of everything for me to continue to try to live. I don’t know how that is to be done and I’m tired of waiting for it to get better and wanting to work for it. It feels so beyond tiring and depressing. And the worst part is no one really cares unless they have some advantage. This is from my perspective. I don’t want to sound cold but that is how I felt for years.
