First I feel like giving you a big hug so here goes!00000
You have a lot of anger and actually that's very good because it is your catalyst for CHANGE.
When things are overwhelming it is easy to feel disheartened and a vicious cycle starts, you need self esteem to be strong and to regain will power, so I would say work on your self esteem first.
You are a valuable, loving mum and forget what you think about yourself, focus on what your dc and parents think of you. Do something nice for yourself daily that doesn't involve food and if you feel your self confidence slipping, jot it down in a diary or write it here.
There are fabulous recipes to try on the internet, even on youtube. Start with finding out where your local Aldi or Lidl is as they have fab cheap fruit and veg.
As I type I have a chunk of fresh cauliflower and whole carrot to munch on. I would say, to start with make it a rule only to snack on fruit or veg.
I took out wheat from my diet completely and don't feel bloated any more, have a go and see how you get on.
I love yogurt with sunflower seeds and a little fruit or jam or honey, I have that instead of big puds.
I don't eat potatoes much any more but I do like a little meat, cheese or fish and find a soup based main fills me up no end, with a bowl of rice or noodles.
I have a boiled egg some mornings but not with anything else, if I'm still hungry I have another egg instead of cereal.
I cut out all processed foods and I feel so much healthier, I don't fry anything as I find it's quick and delicious to microwave some nice cheese with some chopped veg like mushrooms and tomatoes.
If you then add a veg stock cube or soya sauce and boiling water and some rice noodles to a little bit of chopped chicken you are in for a delicious easy and filling meal, especially if you chuck in a small handful of chopped baby spinach leaves at the end.
The thing is, experiment and have fun! Get your children involved and once you avoid the aisles with the nuggets, chips etc you can start enjoying the joys of real food, and everything in moderation.
I enjoy growing veg and if you have a spare window sill or bit of garden it's nice to do.
Please don't be hard on yourself any more as a lovely butterfly is waiting to emerge from the chrysalis you're in now.
Just clear your trolley, cupboards, fridge and shelves of things that aid and abet your misery and have another hug to help you on your way to a new, happier you xxx
