Hello and welcome to beyond blue.
Depression makes us think the worst of ourselves, and displays itself in other forms as well as you are finding out. Unlike a broken arm or similar, with depression and anxiety you don't know how long you are "out of action" for. Will I truly get over it? Or will I just have to manage?
This is not really a question you need to answer here, but can I ask how long your husband has been seeing the counsellor? I have been seeing a psychologist for over a year, every 2 weeks and these things take time. Unfortunately. I am not saying this to make you feel worse. Some people take longer, others shorter. We are all different or unique. I also take AD medication. One of the things my psych gets me to do also is talk abut some of things I talk to her about to my wife so that she gets an understanding of where I am at. Again different people, different circumstances. (And I do not retell the entire session to my wife!)
There are many things that can help us manage with depression. For example, my psychiatrist also put me onto a sleep hygiene thing, because I would wake up in the middle of the night thinking about work. And something as simple as not drinking coffee after 4pm helped. That was only part of my puzzle.
