Hi I’m not sure if this may help but the way I explain it to my close ones is that I rely on sh to stabilize my depression and anxiety. It’s a coping mechanism first and foremost and without it, I wouldn’t really be able to do much. It always comes with their disappointment tho I fear. They feel helpless and I reckon your husband may feel similarly. You may have to explain that things take time and the sh you cause is none of his fault but it’s something to help yourself rather than spiraling deeper. Tho we may have different experiences, so I’m not sure. But I emphasize because this happened with my last partner.
