OP, I can sympathise.
My wonderful, caring, selfless, funny husband had a major depressive breakdown in late 2016, culminating in over two months of in-patient care in a psychiatric hospital. It was the hardest thing we’ve ever gone through.
For me, the worst thing was the selfishness. He’s not naturally a selfish person at all, but when he was sick, he could not even think about anything outside of his own head. I think it was just so hard for him to even put one foot in front of the other each morning, all he could do was think about his own actions, sleep patterns, whether he had eaten or not. It was agonising, and I did lash out at his behavior a few times.
That said, his hospitalisation made me see it a bit differently. In treatment, practically every single decision was taken away from him. He was on a set schedule of waking, breakfast, therapy, lunch, therapy, dinner, expertise, supper, bed. His biggest decision was whether to have chicken or cheese salad at lunch.
This is a man who works in a very senior, stressful job. It was a big change, but he was relieved.
His key worker spoke to me and asked me to keep “real life” stuff away from him initially, and then had he start to introduce things as the weeks went on.
When he came home, it was tough. He was used to thinking about nothing but himself so there were a terse few weeks of readjustment. It was awful.
He’s been out of hospital for almost a year now, and is still in therapy. He’s a different man. He’ll always have anxiety but he knows how to cope with it now. He’s gotten a good balance with anti-depressants, therapy, and lifestyle changes.
I really did struggle. I felt very angry that he got to check-out or life, while I was left to pick up the pieces. I had no family support, but work were very good and understanding.
Anyway, didn’t mean to write so much. I guess it’s easy for people to say “LTB, he’s selfish” (and that’s an option!) but it sounds like you’re determined to make this work and, unfortunately, his behaviour is a symptom and it sounds like he needs treatment above what he’s already sought out.
