There’s a lot going on @Helpmplease.
You may need a different antidepressant. Cymbalta is good for depression associated with anxiety and may cause less weight gain. However, what are you doing to address the underlying causes? Do you have counseling? Have you tried CBT?
Why are you so bored that you end up binge eating? You need more to give life meaning than work, kids, husband and walking the dog… Again, counseling may be helpful, but also look for activities and interest groups that could expand your horizons. Personally I took up painting and started reading again. A friend of mine joined an amateur dramatics society, another is in a choir. There are so many things one can do - there really aren’t enough hours in the day!
Practical advice:
Walk longer and faster, wearing ankle and wrist weights and good walking boots - ie not just ambling along while the dog sniffs every second tree along the way. ( wrist and ankle weights are very effective, and after a while you don’t even notice them.)
Exercise at home with YouTube trainers. Use dumbbells and expansion bands to increase impact. I particularly like Growingannanas. Anna has hundreds of 20-30 minute HIIT sessions of varying intensity, with and without weights. Incidentally, using weights is very important. One day your menopausal bones will thank you! Also, over time, regular exercise will improve your general motivation and positive outlook
Regarding diet, cut processed food right out and reduce consumption of sugar and complex carbs. A moderate amount of simple/natural carbs is fine, ie those found in vegetables and fruit.
As a PP has mentioned, extend your fasting period by having a late brunch and early dinner, with just a healthy snack in between. Reduce temptation by not having ‘bad stuff’ in the house.
Drink lots of water and minimize alcohol. Whenever you are tempted to binge or eat crap, first drink a large glass of water, or water mixed with a little cordial. Eat a carrot if you’re still tempted. Walk up the stairs and back down again. Hang up clothes/ tidy stuff away for 10 minutes. Make a phone call or check your bank balance. In other words, use diversionary tactics in the hope that the urge to be naughty passes… Good luck
