I know this isn’t his quote but he claims her quotes are like “pep talks to him”.
I find this kind of self help tosh really offensive. If you are suffering any kind of MH condition, you may not be able to enjoy life it or taste it for certain periods of it while your condition is waging war.
Similarly, we do have power over our circumstances in some situations and it can be dangerous to assert otherwise. One aspect of depression is hopelessness and helplessness in the face of certain situations and the treatment regarding this is learning to overcome these reactions you have when those circumstances might be repeated in the future.
He is encouraging people here to do things that a) they may be unable to do or b) may contribute further to a MH disorder. Once again, way off the mark.
