This won't apply to anyone else.

Ignore almost everything anyone else tells you unless you can independently verify it, especially your parents. In fact, just divorce your parents now. The correct answers always come from within your own head. Your first impulse is always wrong, but doing the wrong thing almost always turns out well. You're almost always the smartest person in the room, and everyone knows it, so calling yourself "stupid" is calling everyone in the room stupid, even when true. Confidence is key. Talk more slowly. You can't be anyone other than who you are, but you can be the best "you" that can be. Nutrition is entirely applied physics (calories consumed - exertion = weight), so count calories. Yes, you'll live to see 85, and yes, life gets better at 30.
