Maybe dip into a self-help book, to give yourself a bit of a boost? One of the really good ones. Some are useless. Even with the good ones, the effect is - in my experience - temporary.

I like The Power of Now, by Eckhart Tolle.

And 'Self-Help for your Nerves' by Dr Claire Weekes.

Please do go easy on yourself, dear Have Hope! Lasting changes happen slowly...

If you can just improve your ability to forgive yourself for the emotional eating by a teeny, tiny amount, that itself would be a huge achievement!
