The humor's lost on me.
Reading this shit, I see only a poorly-written and poorly-drawn -- but fundamentally serious -- story about a psychologically crippled loser trying & failing to deal with mental illness. Unfortunately, the author doesn't have enough wit or insight to make the pathetic MC's fucked-up situation interesting. Instead, it's just a heap of ugly & unpleasant crybaby garbage.
So why exist? The world would be better off without the MC, without this series, and without anyone who can relate. Buy a gun & eat it, kid. They're hella cheap.
