Purpose is more important than happiness. Having a purpose (or looking for it) will save you. (And sometimes finding a *new* purpose is what you need.)
Everyone has times when they don’t get their way. They lose, or fall short in competition. Everyone fails. Very few are able to fail gracefully, keeping conscious of their their dignity, not losing their sense of humor, etc. Cultivate a resilient mindset. Sometimes if you can’t beat them it really is a good thing to join them. Sometimes it’s better to go down swinging. As far as enduring a bad situation, the saying goes “If you can’t get out of it, then get into it.” Meaning, make the absolute best of it. Excel, delight in your circumstances as much as possible. You won’t stay down for long.
If a girl is drunk she cannot consent. Don’t even think about hooking up when your partner is intoxicated. It’s immoral and illegal. No excuses. No exceptions. . Break this law and you will be (rightfully) charged with rape and you will get sent to prison.

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.
