There seems to be quite a lot going on in your OP.
Firstly I would say that not many jobs have “no time pressure” especially if you want a reasonable salary. You could become a freelance tutor / supply teacher/ run your own business and that might work okay, but you can’t necessarily expect to make as much money that way.
You already know that self-medicating with alcohol is a bad idea. Did you consider quitting alcohol completely?
Are you finding time to get proper exercise and sleep?
Are the ADs a new thing and is that depression entirely work-related? What else is going on in your life, if not?
How old are you - is menopause a factor?
You mentioned dh says you don’t need to work … is it because your dh earns enough to support you both?
How supportive is your dh - some will leave you struggling with children to raise, household to organise, elder care, and all the life admin - and then give you sympathy and make you feel like your only option is to stay home and be a full-time wife and mum. Often the better answer would be they take 90% of the strain of managing the home for a while. So maybe dh goes down to 4 days a week and so do you, and then between you everything can be accomplished more easily.
I wonder if you could consider going down to 2 or 3 days a week and see if that helps rather than quit and end up in a low paid job.
