I didn't read all of the post to be frank, but I think this will help:

Step1- you gotta accept the situation and think what to do.

Step2- calculate your BMR and drop it 500 to 1000calories.

Step3- download MyFitnessPal and set goals with step2 accordingly (aim for Macros 50% carbohydrates 30% Fat 20% Protein).

Step4- collect all unhealthy food in a places preferably a drawer or cabinet, and in the fridge down or back shelfs.

Step5- write healthy groceries for 6 days and use MyFitnessPal to know the calories to know how much to buy. (Examples bananas, apples, cucumbers, tomatoes, broccoli, zucchinis, olive oil, 0 fat marketed cooking spray, low carb protein powder, eggs, chicken breasts, tuna, rice, "peanut butter", rolled oats, almonds, brown bread, coffee/tea/ herbal teas...etc).

Step6 - make 5 healthy meals Breakfast (e.g. 1/2 rolled oats 1 cup full fat milk, microwave for 2min 30sec, add 1 banana and 1tbsp honey.)

Snack1 - (e.g. fruit nuts with egg sandwich/es and a cup of coffee)

Lunch - (e.g. 1 cup rice 1 chicken breast/can of tuna drained 1 cup vegetables all boiled)

Snack 2 (e.g. protein shake 1 scoop 1cup milk 1 frozen banana)

Dinner (a salad with olive oil)

Step7 - choose a day of the week and eat anything on it, but stick to it don't change it.

Step 8 - weigh yourself weekly.

Step 9 - meal prep for 3 days so it will take 2Hours each week to prepare.

Step 10- watch success stories to stay motivated.
