Having the trifecta:- depression + anxiety + ADHD...how to cope?

hey all, my spouse (recently dx ADHD last year) is really struggling and I find myself getting more and more frustrated with him. He has anxiety, depression (the chronic, hardcore kind) and ADHD. His brain spins out all day, every day. He's addicted to his devices. He doesn't exercise and he doesn't eat right and he doesn't look after himself. Most days I can't believe that his body allows him to function.   Every day for our house is ruled by his emotions and feelings and whichever of his challenges wants to rear its head that particular day. And its a crap shoot for the rest of us living in the house too. A real gamble and to be honest, feels like neither me or my son can actually be able to have feelings, a good day, bad day, etc because we just don't know how my husband will present each day. 

One day, it's his ADHD that rears up and we have to pay the 'ADHD tax' and I find myself frustrated as its an avoidable thing, but he doesn't want to see it. And then the next day, he will wake up, seem to be engaged and coherant..only to be triggered by something and he's back in the bed for the rest of the day or a few hours...and we all have to tip-toe, work around and make conncessions for him every day, every hour. he promises something one evening, and when I ask about it the next day, he will state 'I was only talking outloud'. Doesn't committ to anything. literally anything. 

But with it all and its frustrations.... I find myself really sad for him and pity-ing him and that's not a great place to be for us as you might know.  His depression is horrific to experience. I'm sure it is horrific and horrible for him to have, but I am impacted by it too (as is my son) and this way of living is not something I wish to continue much longer and making plans to see what my options are. But he literally can not. get. out. of. bed. And he says how he doesn't feel like it, he's tired, he's sore, etc....and there comes a point when I think you have to put two feet in front of each other and get the f**k up and trudge on and do that the next day and the next. And to be honest, if you aren't living life and aren't able to actually FUNCTION at all any day or any point... then there needs to be an intervention and help. 

I guess my biggest wonder is: what can I do (if anything) to support him besides just living my own life and trying to live in my values/boundaries (which he constantly ignores because he's struggling so much he asks for help on so many things...every day...every hour). I mean, I feel like I'm living in a life sucking vortext and trying not to get dragged down. I don't want to tell him what to do but there is SO MUCH HELP AVAILABLE and it's incredibly frustrating to see him struggling and making his - and our - lives so much harder than what they need to be. And if I'm really being honest: I've been his caregiver, nurse and mother for far longer than I expected and signed up for. It sucks. 

 

......now that's i've typed that out... I can also see and ask myself what my ROLE is in it and I do believe I have enabled him greatly and I'm angry at myself for that too. But it's so freaking hard to untagle the enmeshment that we've built up. 

HELP!
