With the comfort eating (I do that too!) I find it easier if I don’t have the treats in the house at all. Then when you get the urge to comfort eat maybe there’s a way you could treat yourself in different ways e.g a nice bath with candles, a lovely cup of tea etc. Dark chocolate is my go to when I really neeeeed something, as it’s good for you, right? 😉
The heating and very hot baths/showers make my skin dry at this time of year. Drink lots of water and try not to have water too hot.
Finally on the stress, meditation might be something that could really help you. There are lots of different ways to do it, from a mindful walk to a guided meditation on YouTube, sitting quietly and really focusing on your cup of tea, or things like yoga and Qi gong, so you can try and find what works for you. I’ve recently discovered Qi gong and it’s really lovely! Lots of 10 minute beginner practises on YouTube.
Gratitude diaries are meant to be good too, where you write 3 things you’re grateful for each day. I do this every now and then but not all the time.
I’ll be watching for more ideas too, I think self care will be really important for us all this winter.
