How was a young person's life in East Berlin different from yours?

They couldn't have posters on the walls of their bedrooms or really stand up for what they wanted to. They were constantly spied on by  the secret police force, even more if part of their families were in West Berlin or West Germany. Their adult life, as well as their chances of getting into college, could have been sabotaged by the government.Their whole lives were documented in extensive files that the Stasi had collected. Some of them weren't allowed to walk out of their front doors without facing punishment. They had no freedom of speech or protest and they would be killed if they were caught trying to leave the country.
