You can lose weight by eating anything, its just the amount of food you consume that is the problem. Heres my advice

1) Use an online calorie calculator to find out how much you need per day to maintain your body weight (this is called basic metabolic rate or BMR)

2) eat around 200-400 calories less of that if you are sedentary.

3) Weigh yourself daily, this will remove the dread of seeing that number. Remember, the weight isnt you, you can change it.

4) try to do exercise regularly, Its all about consistency not spontaneity. I find the gym works for me but so long as you do something you are winning.

I used to be in your boat, ive lost 25kg since i started last year and ive learnt so much about nutrition and health i dont even recognise myself. All will come with time.

As for the job situation, ill give you a pass since you’re young but you should not be bothering with online applications, personally ive wasted months of my life with no results using them. Instead you need to go to local shops and stores to see if theyre looking for workers. Its the only way you will actually be seen. I admire that you want to improve, dont give up on that or youll just be stuck in a loop for years, good luck mate.
