Sometimes I'm so damn stupid that I can't take myself seriously. As a result I got self-ironic instead of self-critical over the years. Perhaps I'd be already dead if I wouldn't be able to laugh about me and even about the depressive episodes I had in the past. When I thought about 'signing off', there was that voice in my head telling me that only people should kill themselves that already lived before. Then I started a polemic with that inner voice and eventually I got so crackbrained about that inner dialog that I started laughing. End of the depressive episode for the moment.
Maybe there is a guardian angel, but I got some type of 'Cheshire Cat' instead. But then an invisible cat might saved my life a few times so far.
