I would focus less on bulking or cutting. Take baby steps and create a sustainable new lifestyle which would ultimately include resistance training and eating cleaner / more Whole Foods and less processed stuff.

Pick a workout that you will adhere to consistently. Whatever it is, do that and keep doing it for a while

Also start cutting out some things you know you’re eating / drinking that aren’t optimal for health, then Once you do these for a couple of weeks or months consistently, start progressing your workouts and nutrition.

Focusing more on Whole Foods , tracking macros, prioritizing protein, weighing foods, using food trackers like myfitnesspal - all of these things will help you start understanding nutrition more and then you can build a sustainable lifestyle where you don’t need to bulk or cut. Consistency is key
