I enjoyed reading your journey on eating. I can understand the headache of working as a chef, I've seen them in action because I've worked in hotels as a server and it is hard work.
Although, I'm not a chef, people used to praise my cooking: they even said I should open my own restaurant. Like you, nowadays, I couldn't care less about cooking.
I go to restaurants now and then, but I usually have supermarket soups and I make delicious salads from scratch. Oh...and I normally fast each day...no breakfast...no lunch, just pure green tea or lemon water.
Besides, life's too short to be in the kitchen toiling in a job you fell out of love with. It's good that you followed your heart and doing what feels good. It's the only way to live.
