You have to fight for yourself and your family. Why were you in school, to learn what you could/wanted, not get a particular grade. I am in a school in a foreign country at the moment and they grade differently than I am accustomed so my grades are much lower than I have ever gotten. I was thinking of dropping out but then I remembered what I was there for, and it is not related to what they are doing/there for.

Other people have to fight their own battles or they cannot learn to live in the world and we cannot be around for them all the time because we have to live our own lives and fight our own battles. To assume another person wants or needs you to fight their battles can be seen as arrogant and condescending too (my husband taught me that; he does not offer to help other people, waits until they specifically ask for his help and then helps gladly).
