B.B.
Can’t help but recognise a few of those symptoms in myself recently. My depression and lack of enthusiasm for anything had come from a long period of stress building up within my body over time, this affected my thinking which in turn was starting to affect my relationship. It is not easy to recognise this in yourself and sometimes very difficult for others to see what the issue is too. By chance my wedding anniversary had come up and my wife booked us into a Spa for the weekend. Was the best thing. Time away from the usual surroundings in the middle of no where, nothing to do but have massages, swim, sit in the sauna and steam room and spend a lot of quality time with my wife. It completely relaxed me and gave me focus, perspective and energy again, which I did not expect. Not saying this is your solution, but something to think on.
