Oh dear, you do sound down! First of all be assured it WILL get better, I think most of us have gone through this at some stage but of course when you have family and have to work too, that's not much consolation
. Just a few points that spring to mind:-
In our case, after trial and error, we found Humphrey was better when it wasn't totally pitch dark so I started to leave the blinds up at night.
I know lots of people don't leave water down at night, - personally I totally disagree with that, particularly if they're fed dry food.
If you can, try and wait for a break in the barking, and then go to him if still necessary, that way he's learning that being quiet will get him more attention.
So difficult when you're tired and probably a bit grumpy, I know, but do try and stay as calm and matter of fact as you can, they're so quick to pick up on any tension and become more unsettled.
Perhaps you can arrange some sort of rota with your husband on a weekend, so that you can get at least one good nights sleep? It isn't going to be a permanent situation but it might just help you get over this stage.
Chin up, - you'll get through this, hopefully someone else on here will have tips about what worked for them. Best of luck!
