We are all human beings, and we all have insecurities, but it's about being healthy and happy with yourself. I'm not perfect, and I will indulge in pizza and sweets on occasion. The goal is to make the majority of your decisions good for your body. So listen to your body, and treat it like your temple.
A healthy friendship is one where you share your true feelings without fearing the end of the relationship. It's also one where you sometimes have to let things that bug you slide. The tough moments will make you wiser about yourself and each other. They will also make you stronger and closer as friends.
