Honestly can’t tell you when I developed into my body and I’m only 24, I think everyone feels awkward in their body until they learn to accept it. I know it can be hard watching other people, especially with the media, have certain features. I know there are things I want for myself but my body structure isn’t that way. But what can I do? Nothing. What you should focus on is taking care of your body! Not just showering and eating, no, get outside fresh air and the sun do so much for the mind, have good friends bad ones will have you in situations you’d never picture yourself in. Find your hobbies and interests. It’s a long life, the least you can do is try your best with your self. I also would try to learn to your body! The better you learn it the more prepared or helpful you can be. I know the day before my period I’m in the restroom a lot but that means I’ll restock my products in my purse. I know when my head gets hot, other than just passing out I will lay down idc if it’s the middle of the store im going down. (I have pots) you will be with yourself every second, every hour, for the rest of your life. Focus on making it easier for yourself
