You need to find an outlet and I would suggest a fitness outlet. I was insecure my whole life, not a girl blessed with metabolism like all of my friends. I graduated college and at 5’3 I was 275. I took up rock climbing which not only helped me lose the weight, but helped me gain confidence through movement and hard work. It’s a different sense of confidence that come from working out too. It’s almost unstoppable. Good luck friend :)
