Suggest me a book about someone who reached greatness from humble beginnings after struggling with huge responsibilities.

Sorry for the vague title.

I have been struggling with the "weight" of the world so to speak. I am a widow, having lost my husband 2 years ago and since then having everything be my responsibility has been weighing on me greatly. My parents were abusive so I don't speak to them, my husband's family doesn't speak to me since they never liked me cause I was a foreigner so I am left to manage my household, my dreams, my work, my money, everything. I have close friends but they tell their SOs everything I tell them so I cant really share with them.

I recently read about Kaiser Wilhelm II and how much of a weak man he was unfit for the responsibility of ruling an empire and that helped me with motivation "at least I am not as bad as him".

So anything historical like a biography of some great person man or a woman who rises to the occasion after having to overcome insurmountable odds.

However, it doesn't have to be a biography but memoirs or anything real.

Thank you!
