In the era of social disorder, my father mistrusted other people, causing the company's stock to crash and becoming the innocent victim of the darkness of human nature.
This makes no sense. If he "mistrusted" other people, he would have avoided dealing with them, and could not have been taken advantage of. I think you mean to use a different word.
As for me, because I grew up in a family of distress, I matured mentally faster than other people of my age. I became very independent, hardworking, and determined, trying to not become another cause of stress and burden in the already-hard lives of my parents and my brothers. While keeping up my academic work, I tutor everyday afterschool to earn my own allowances and provide the family with my little pay.
Everything up to this, while sort of interesting, tells about your family. This is the only paragraph that talks about you, and you are supposed to be the focus of the essay. So, you need to explain in much more detail how this experience affected you. Also, this seems more like an experience, rather than an "issue," though I suppose you can technically use it.
