There was a poster that wrote that she asked her daughter to stop worrying as obviously to her as it was affecting her anxiety. I find that a smidge worrying.
I am sorry, I should have given more detail. The daughter is an adult (23) and I am there to listen to her day and night if she needs it. She knows she can ring me in the middle of the night and does so. I have spent many long nights holding her and listening to her. She talks to me in great detail about how she feels and that is good. I fought hard to get her therapy. She knows I have her back.
It was just that I did find it stressful to hear all the details over and over again about the man who had stood in the queue behind her had coughed, and would have given her corona. I listened for the first 10 times or so, then I asked her quite gently to try not to think about it because it was getting a bit much. (Both dh and I are vulnerable so hearing over and over again how this disease would be coming into the family was quite stressful even though I haven't actually got health anxiety).
Oh and by the way, I found what you said about children killing themselves being the fault of parents not listening quite upsetting.
My dd did attempt suicide several times during adolescence. It was not because I didn't listen to her: it was because however much I listened I wasn't able to take her pain and fear away from her. By the time she made her second attempt she was in therapy with a very helpful and understanding team: she just had a bad flare-up. Parents fighting to help their suicidal children have a hard enough time anyway: they don't need people to suggest it's their fault.
In the case of adults, I think it's a question of compromise. Your husband should listen to you as his default position but should also be able to say if he is getting stressed by e.g. hearing the same worries over and over again. I assume you would expect the same consideration from him. If something is already worrying you, would you want him to keep talking about how dreadful it's going to be?
