hahhahah yep, sad but true! The unhappy thing has been labelled "The Pain Body" this is like the emotional side of ego and is exactly what you describe about the "im not good enough" thing. I think it stems from our minds always looking for dangers like a sabertooth tiger from back in the caveman days (if that even happened who really knows?!) but these days we have no threats like this so the mind is left with not much to do, so it creates threats that arn't real :)
