Beauty tips

Hey loves. Probably it sounds desperate but i want to talk about this. Next year I will go to university so I’m studying for the university exam. And that’s why my life is so stressful right now. And when I’m stressed, I eat. That why I’m dieting right now, but also I really need beauty tips bc I really feel ugly. Most of my friends are tiny, healthy and beautiful. And I want to look like that. So pls, help me?? (When I said Beauty tips I mean: make up tips, or tips for diet, etc.)
