Oh shit, you mean it's just like depression ? You can just decide to not be bothered by it ?

Why is nobody talking about this? it sounds like a revolution for mental health, this could wipe out the need for therapy entirely.

edit: OK so that was possibly a bit unfair, i recognise that aspects of mindset and choice are part of it, but your answer was so much like telling clinically depressed people "Have you tried just not being sad?" that it rubbed me the wrong way.
