stressed about dieting and weight loss

I have moments where I think I look beautiful and I love my body and then I have moments literally a few minutes after that make me hate my body. I tried to lose weight by using a diet tracker, but it just stressed me out to the point where I was tempted to stop eating meals. I've been in the process of doing exercises at home and I've been watching what I eat more, but not starving myself. For example, I'd still eat sweets. I'd just eat a smaller portion of it. Water has also been my friend lately. I allow myself to have one glass of whatever else I want to drink at dinner with the rest of my drinks being water. I tried my best to follow the diet tracker. It made me cry and think even worse of myself.
