I guess a lot depends on how far in the past - if I could talk to my child self, I'd tell her to try to enjoy everything more and never expect friendships to last forever. Also try to save the Microsoft Word journals on USBs, and keep the physical journal far away from our water bottle. Not all your friendships will last forever, and no, you will not always remember what being you felt like as though you were living it. Memory doesn't work in practice the way books make it out to, and neither do social interactions. The relationships she sees on iCarly are abusive. Not being friends with Grace would be worth the loneliness. The world is so much larger than this neighborhood - Dedham Street is not actually the edge of the world, but keep scootering through the neighborhood picking up trash. Nobody else will.
If I was talking to my teenage self, I'd tell him to keep in mind that his body is not going to be the way it is forever. That while months and years felt like forever, they weren't, and so he should have never tried to make that permanent decision he tried to make when we were fifteen. I'd also tell him to take more pictures of his friends, and copy his favorite school essays into Microsoft Word documents since he will lose access to the school Google Docs account upon graduation. He mostly made good choices, my teenage self. I'd validate that fact.
