There are many things to remember when your mom has an outburst to help you stay calm. It can be difficult but try not to take anything that she says personally. Keep in mind that she’s having a hard time with it too and that it’s not anyone’s fault. Avoid arguing and trying to convince her that her delusions aren’t real, as this will only cause stress. Try to find neutral things to talk about to avoid frustration. It could also be beneficial to seek a professional’s help in coping with this.
