wouldst thou like to live deliciously?

And that was only until the end of book six. After that, he was even stripped of everybody he could ever show a tiny bit of his true self, forced to lead a school that was suddenly following DE rhetoric and teaching (and using!) unforgivables to/on the students.

It's an absolute mystery to me how this man persevered as long as he did. How he was mentally, but especially physically, able to accomplish all of that without slipping up even once. I'm burnt out only from thinking about going through that. What an unbelievable accomplishment...

True, because:

Harry found refuge at Hogwarts, where he felt welcomed, supported, and protected from the very beginning. Severus did not.

Harry had adult figures who protected him, cared about him (Hagrid, the Weasleys, Dumbledore, Lupin, Sirius...), and showed him affection over the years. Severus did not.

Harry had two friends who would have torn apart anyone who dared to strip him in front of the entire school. Severus did not.

Harry and Malfoy had a rivalry because they were on equal footing. Severus was bullied by a group of guys who attacked him together and were far above him socially and economically.

Harry was rich—disgustingly rich, to be exact. Severus was disgustingly poor.

Harry felt loved from the moment Hagrid came for him just after his 11th birthday. Severus never felt loved in his entire damn life.

Harry was favored by Dumbledore and other school staff on multiple occasions. Dumbledore forced Severus to stay silent about an attempted murder against him.
