Hi OP. It is perfectly possible to lose weight if you want to. I'm firmly menopausal at 46 and can lose 2lbs.a week. But you have to really want to.
I also still eat chocolate when I'm calorie counting (though these days I don't like sugary stuff so I eat 90% choc - about 300 cals of it every day). I also have the odd drink, but the hot flushes aren't worth it!
Regarding water, I drink two pints to start the day at the sink, tepid tap water, I just down them. I then have a litre bottle that I drink before lunch and another after lunch. Plus the water in tea and coffee will help, and then another pint with dinner/overnight.
Definitely shave your legs and paint your nails. I always know I'm a bit depressed when these things seem pointless and like too much effort.
Wine before bed is a nightmare for sleep. If you need a drink, have it at 6pm when toddler is in bed, then switch to mint tea. Or I love fennel tea. Or get some fresh mint cheap in the supermarket and make your own mint tea.
When I was in my 20s I got to 12 stone and my GP, very kindly, told me I should think about losing weight. I am 5ft6.
I went home, joined weightwatchers online and lost 18lbs in 12 weeks. I then repeated the Ww after my two children were born. It is doable but you need to want to achieve it. Not suggesting this is right for you, more to prove that it can be done.
Re clothes, can you afford a few £ for something from vinted? I bought a beautiful zara blouse for £3 last week. If you know what size you are, I second the PP above to buy something in the size you are now.
I hope you read this when you wake up and feel a bit motivated. I posted on here two months ago under a different name, because I was feeling very down. Some incredibly kind people took the time to help me with suggestions and it was like a little mini lifeline.
