If it can help, you will never feel whole. Because even if you will be whole, you will want to erase that feeling of being whole, wich will make you empty.
I know being young sucks, I'm also still a teen, but hey, this is the time we can actually do shit and get away with it. You should try to make as much use of the world as you can.
And I don't mean "yolo" or something, you can quietly learn a language, learn how to program, do something with your life and nobody will ever know. But then one day, you show off your mad talent and everybody will be impressed. That's when you will feel human and you will feel something. That you actually can do something other people can, that you impressed others for something you worked hard on. But most importantly, you improved yourself and in this world, thats a huge thing. So hey, learn something, explore something, be something and become someone.
We're all still young because the amount of knowledge there is just so much, I will always feel dumb.
