A fat teen girl can begin her self - acceptance journey by understanding that beauty comes in all shapes and sizes. She should educate herself about body diversity. For instance, she can read books or watch documentaries on the topic. She can also start a journal where she writes down all the things she likes about herself, not just physical but also her personality traits. Moreover, she can join support groups or online communities of people who are also on a journey of self - acceptance. There, she can share her experiences and get support and advice from others who understand what she's going through.
Well, first of all, she should surround herself with positive people. Family and friends who love her for who she is can make a big difference. Then, she can try to practice positive self - talk. Instead of saying 'I'm fat and ugly', she can say 'I'm unique and I have so much to offer'. She can also look for role models who are body - positive, whether they are plus - size models or just confident people in her own community. By seeing others embrace their bodies, it can inspire her to do the same.
