I need a healthy diet plan badly

I want to change something in my life and I want to do it right now. I am sick of everything and I have even thought about forfeiting my life several times. I am constantly depressed and it is all because of the fact that I am hideous. I may not be the most dreadful human being but I am fat and I hate it. I was not that fat when I was younger. Frankly speaking, I used to play football and I was well-built and my cardio was top-notch. My football skills were second to none as well. I do not even know why and I do not even know when it happened, but I started to put on weight drastically. I obviously started eating junk food and stuff. I think the main reason for me eating this junk food was the fact that they got rid of. By "they" I mean the people from my football team. I remember that I failed one match, only one! That was probably the reason why they got rid of me. It was a huge hit in the face and I started to eat badly. Now I need a healthy diet plan badly because I cannot stand myself anymore. Whenever I see this huge belly in the mirror I want to punch it as hard as I can. I am determined and I think that if I find a proper healthy diet plan I will definitely implement it.
