I failed at everything. Is there any good reason not to kill myself?

I've tried cultivating indifference, but still the tiniest things cause me immense pain. Today my manager gave a lecture, without raising her voice, about something I did wrong at work. It hurt me so much I spent ten minutes at the end of the day crying in the bathroom. I have no social life or dating prospects because I can't drive and I'm too scared to learn. I don't see any reason not to give up and kill myself, except maybe that it would hurt my friends. I can't even get myself to neutral. All I can manage to reach is a facade of "coping" that conceals from others and myself my inner insecurity and deep desire for death. I recently started a new job after being unemployed for years. For awhile that was making me feel better, but I've returned to my normal self-hatred and more-or-less constant sadness. I have a deep desire for someone to care about me that I wish would go away.
