Too complicated

Harry could accept the death of his parents, it was difficult, but he didn't even remember them. He could accept life with the Dursleys, because he could not avoid it, but when his godfather, the only native person, Sirius Black died, for the first time he did not know what to do, life seemed to have lost its meaning. He knew only one thing - Voldemort A must be killed. At any cost. This monster cannot live. That's why, when he couldn't sleep properly because of nightmares, the first training sessions began. It was impossible to conjure on the conicles, so it remained to read textbooks and start playing sports. Despite having a toned body after playing Quidditch, he was able to squeeze me only 2 times and run 2 blocks. But it was not in his principles to give up, and for a month and a half he actively repeated and taught what they were going through at school. In the process of reading textbooks for the first courses, he learned and understood a lot, what he had missed because of his experiences was rapidly catching up, but he felt that this was not enough. It's not enough to know the school curriculum, you also need to be able to use household spells in an emergency. But he decided to do this at school
