My partner has what I consider to be moderately severe mental health issues - ADHD with emotional dysregulation, and anxiety/panic attacks with catastrophising/cognitive distortions.
The first part of each of those is his actual diagnosis, the second part is me highlighting the part I want advice on.
When we argue, and I try to point out that some of the issues he is raising, and his emotional reactions to them, are related to or exaggerated by his mental health issues, he gets very upset, says I'm just deflecting from my own faults and behaviours, and claims that he does not have any emotional dysregulation, does not catastrophise, and that there is nothing wrong with any of his reasoning facilities or the conclusions he reaches.
I've agreed to stop mentioning it, because it clearly doesn't do any good and just makes him more upset.
Does anyone have any strategies that have worked to create a more harmonious home with someone with these issues?
And because it's always asked, no children between us.
