How can I make up my mind to lose weight?

Because there is a baby with a fat face, when I go out, I am always jokingly called Little Fat. I have tried to lose weight, diet and drink green juice countless times, but all kinds of methods have not persisted. Probably because I don't feel fat in my heart, I keep eating and eating, and I will still be called fat every time I go out, so I wish me happiness in my heart. Until I met my boyfriend some time ago, he always called me fatty. So I made up my mind to lose weight, because I wanted to lose weight quickly, so I chose to take diet pills taken by my best friend. When I really lost weight, my face became smaller and my double chin disappeared. I used to wear jeans that could never be buttoned, and the meat on my walking legs would not rub. When I put on tight clothes, my waist became thinner. When I go out, I am always surprised to be asked why I am so thin, so I want to tell those girls who want to lose weight, whether because you care.
