I've personally never really seen the appeal to existing in this world. Life is tedious, useless and unnecessary and it all leads to nothing and nowhere apart from existing beings inevitably deteriorating from age. Humans do repeat the same tasks again and again, they are slaves to their needs and desires, it's like they are blind to the fact that life is completely worthless.
But yes, it's a burden being conscious and aware in this world and I know that no matter the circumstances I could never be close to being content with existing. For me the problem lies in life itself and I view it as always being preferable to not exist altogether, so your feelings are very much understandable. I hate how people insist that "life is a gift" and is "always worth enduring", but there is really no valid explanation that isn't centred around delusions to support those claims. Life is certainly boring, but has the potential to be way, way worse than that. It's true that life in itself is suffering no matter what.
