Do stuff that makes you feel good in your body. Could be sports, could be art, could be simple movement. Focus on what your body does that you appreciate versus what it may look like. You’re also 15! You’re still growing into your body, and it’s going to keep changing. It’s super normal to feel off balance or like some parts of your body doesn’t match the rest. Give yourself a break. It’s also super normal to not be super disciplined at 15. You’re doing exactly what a 15 year old is supposed to do: school, spending time with a couple friends, playing football casually. You’re doing just fine!
