I hope you don’t have to struggle with your weight. For me it’s been a lifelong battle. Some things I learned are: Listen to your body and eat when you’re hungry. Eat as many vegetables as possible. Ignore the scale and focus on other goals, ones that are in your control such as how long you can run (or dance, or row, etc.) Reading a book instead of plopping down in front of the tv with a bowl of ice cream, saying “no thanks” to a treat. Focusing on pounds lost or gained is deflating. Stay in good shape for as long as you can! Make your health a priority. It’s much harder to get in shape than to stay in shape.
Think about building a career. Take low-paying or no-paying jobs that will give you the experience you need to build it. It's not all about the paycheck, especially when you're young and don't have too many bills to pay.
Sit down together and write house rules on anger. We don’t hit or bite. Do we yell and slam doors? Name-call? Say “I don’t love you” ? Bad words? What’s appropriate anger and what’s unacceptable?
Glennon Doyle described a conversation about explaining to a child what "sexy" means: “I think most people are confused about what 'sexy' means. Sexy is a grown-up word to describe a person who’s confident that she is already exactly who she was made to be. A sexy woman knows herself and she likes the way she looks, thinks, and feels. She doesn’t try to change to match anybody else.
“And she knows how to use her words to tell people she trusts about what’s going on inside of her. When she’s angry, she expresses her anger in healthy ways. When she’s joyful, she does the same thing.
“She doesn’t hide her true self because she’s not ashamed. She knows she’s just human—exactly how God made her and that’s good enough. She’s brave enough to be honest and kind enough to accept others when they’re honest. When two people are sexy enough to be brave and kind with each other, that’s love." (The quote is longer, Google to find the whole thing. Wise words on a tough subject.)
One of the funny/sensitive things about puberty is that kids can be the same age chronologically while being wildly varied in terms of development. Kid might be 6 feet tall in seventh grade or be a senior in high school and still not shaving. Everyone is self conscious, praying to avoid embarrassment. It’s all just part of growing up. Be kind to yourself and to your equally mortified peers.
