It's depression coupled with something else.
Pretty much, it's pretty obvious he's got mental issues and it's just gotten worse and worse over time, leading up to this. I do believe he intends to fix it, and hasn't taken the money, but the attention seeking behavior in this and the other thread just reeks of a cry for help.
But really, need to nut up and stop making so many excuses. Medical issues suck but theres nothing stopping you from handing everything over to a reputable person (several have volunteered already).
