OP you sound very like me - same life style, same boredom issues. I do bootcamps which I've grown to love but they make me fit and strong not slim due to my overeating although I've not gained weight since starting them, despite not changing my eating habits, and I did lose a stone initially but then plateaued.
I agree with PPs that we need more stimulus - dopamine hits from other sources. Can you get out in the evening a few times a week or do you have DC to look after?
If you can't, try listening to fitness podcasts and affirmations. Even watching fitness videos without doing them stops you wanting to stuff your face.
You could also try some immersive mood experiences, like listening to Beethoven's 5th in the dark or taking a blanket into the garden to stare at the stars or having an epsom salt and essential oils bath by candlelight - that sort of thing.
For me the danger is trashy TV. I get up every ad break to stuff my face. Better off tuning into a film that has no breaks and is so engrossing you don't pause it.
If I remember to, I pre-empt the boredom binges by laying out big mugs with fruit tea bags in so every time I come to the kitchen I make a fruit tea instead of food.
I do also do lots of micro workouts like high knees or jacks while waiting for the kettle. That gives you a bit of a dopamine hit too.
The other thing I do is try to have some snacks in that hit the spot but aren't too high calorie - Fibre 1 brownies work if you are craving chocolate, and they're only 100 cals. Same with mini packs of jaffa cakes (I know they are empty calories and give a sugar rush but if you are being honest with yourself it's better to go straight for the 100 cal chocolate sugar rush than have a banana, then a bowl of muesli (about 500 cals) and still want that bloody chocolate.
