You know I've been feeling exactly the same recently and i used to love cooking, but lately I've been stressed out and it's felt like a chore, so I get where you are coming from.
It was getting me down as well (also affecting my health) so I deleted my just eat app, that helped me.
I then had a big clear out of my kitchen cupboards and did a big online shop so that I have access to food whenever I need it, and then it's easier to cook or plan for dinner
What I find useful is watching YouTube cooking videos (especially from around the world I added a couple underneath if anyone finds them of interest?) I find them relaxing and enjoyable to watch and it always gives me fresh ideas (and renewed enthusiasm) for doing things myself.Also they don't have to necessarily, be stereotypically healthy (the recipes) not to begin with, it's just getting used to the idea of food being a pleasure and fun to create.(That's what I found helpful anyway)?
I also comfort eat, so I find that using subliminals, rife frequencies and morphic field healing (all available on YouTube) has helped me, for example with root chakra issues, linked with digestive issues, feelings of fear or insecurity etc, also I use fast metabolism subs, getting rid of subconscious blockages subs and ones for body healing...for example core strengthening, automated body workout, anything connected to stomach issues (big problem for me), also ones to combat depression and cultivate a more positive mindset, and also subliminal's for manifesting law of attraction, cultivating a more abundant mindset.
They help me, I hope they can help others as well
sometimes anything is worth a try? That's my mentality anyway.
Good luck with anything it's normal to get stuck in a rut, or get sidetracked or even despondent (happens to me quite regularly) but there is always something to be learnt from every experience, and I think it helps to visualise a better future (which you are already doing) and to take active steps to manifest that.(I know you are doing that as well, so give yourself some credit)..I know easier said than done sometimes but the mind is so powerful that really tbh anything is possible (yes I really believe that) I do believe it's possible to reprogram the subconscious, the issues that have been holding us back (for example) will come to our attention, but those are areas that need love and acceptance.
Ok TMI but for me a big issue was being controlling (not wanting to let go) manifested in my body as chronic haemorrhoids, also sugar cravings, which showed up as a problem with candida and gut health...why sweet things what was j missing in my life for example? Maybe loneliness or frustration or boredom and then sugar giving me that temporary high? The irony in all of this of course being that ultimately comfort eating makes you feel very uncomfortable the opposite state to the one you want to be in! I won't go on and on (I probably have already
sorry) but generally speaking I was in bad health because everything is interconnected, and previously I hadn't been listening to the (distress) signals, the great thing is though is that if you focus on one issue (the most pressing one) then it has a knock on effect and then slowly but surely everything begins to heal.
