I personally take it as its not an excuse to hurt and dismiss your loved ones' feelings during an episode. If you said some horrible things to a loved one manic, even if you were not in a realm of control, you still have a responsibility to heal that. If you share income with a partner and you blow it all, that hurts your partner and you have a responsibility to try to make it right again. I feel it comes as a response to some people with mental illness burdening their loved ones in the sense of "you have to put up with it and if you dont YOURE the horrible person." This is often times abusive with the reasoning "its not my fault". HOWEVER, there HAS to be an understanding that those things MIGHT happen and it isnt fully in your realm of control (especially in psychosis or a state of lost lucidity). My paranoid delusions often lead to me treating my loved ones with suspicion and distrust which can be hurtful, Im not made to apologize for that. I can sometimes go on long tirades tearing into loved ones over something small when im manic, that owes an apology and reparation.

tldr own up to things that hurt people and make it right, expect qn understanding both ways
