I used to always lay in specific way to avoid looking "bigger". years ago i thought that if i had abs my tummy would be flat all the time. but that's not true at all, in reality we all have tummy fat. our tummies bunch together make rolls, our skin bends. we all have different bodies.
don't let the way you feel about your body stop your from enjoying yourself. don't let your insecurities stop you from making memories. cause in afew years you want to think about the fact that you left early because you didn't feel good about yourself or because someone took a "bad" photo of you. next time you feel this way remember that you are your own worst critic.
our bodies look different in different positions. neither is worse than the order just because one isn't glorified on media. your body is normal. your body is worthy. you do not neet to change your self. you are absolutely amazing the way you are.
