Most heroes, going back long before superheroes to the time of Hercules, have been orphans in some form or another. They've either lost their parents, been sent away from their parents, or some variation therein. In literature there are very few examples where orphans are just seen as regular characters, there's always something special or ordained about them typically. That to be an orphan means overcoming great odds on one's way to greatness. And while inspiring, it can also get a little daunting and triggersome at times too.
Yeah, losing my parents has pushed me to achieve all that I can. You could say I'm a lot like Jackson from Teen Wolf in those regards. But, it's not always mentally healthy pushing and shoving myself to make people who I've never met proud. It always has to be more and more and more and higher and higher and higher. And granted it's gotten me far, sometimes I'm afraid nothing will be enough and I'll always need to go to the next level due to these "great expectations" from my bios, adoptive, and what society at large has proposed since the days of Hercules - that we need to hit Mount Olympus or it's not good enough.
