There's a lot of negativity here. Here the good news- your weight is 100% in your hands. As is your daughters. You haven't been told either one of you has inoperable cancer. Throw away all the chocolate, sweets, fizzy drinks, processed foods, crisps etc.
You spoke about eating crappy foods cause you were bored, why not counteract that by spending time cooking a lovely healthy meal.
If I've misread this and you in fact don't have a lot of free time, utilise your freezer and some Tupperwares.
My partner was 100kg and managed to lose everything and got down to a very healthy weight. He started with diet and when he lost most of them started going to the gym to build muscle.
Eating fish, chicken and rice with veg was his go to. It's very easy to cook but if you are having a manic day, you can always grab some uncle bens, a pre cooked roast chicken and microwaveable veg (2-3 mins in bag).
Not only is being healthy in your own hands, it's super easy and you'll probably save so much money in the long run :).
Try and avoid snacking etc, three decent meals for breakfast lunch and dinner is the way to go.
I strongly believe that if you make a change, start eating healthier and also do some sneaking throwing out of any nasties, you're daughters health will also be positively effected.
Atleast you can ensure she has access to healthy and wholesome foods :).
And don't feel hopeless and say it's too late for you, it absolutely isn't. I promised if you keep up going to the gym (although it's very expensive haha) and long walks etc and also eat simple healthy food you'll lose weight yourself and set a shining example to your daughter ❤️
Mind and body are so closely linked, this means you'll also feel great in yourself.
