I had a sick parent all through college (diagnosed freshman year) who died in my junior year. I am writing an addendum to explain my 3.46 GPA, how detailed should it be? Should I include every major event that affected my schoolwork or a simple timeline of what I had to deal with? Do I explain how my priority wasn't my schoolwork but to my family for basically my entire time at college? I just want to know the proper way to do this without it sounding like a sob story.

I took 2 leaves of absences when my mom died but she was sick my entire college career which deeply affected my GPA. Do I include it all into the character and fitness response or do I write an addendum as well.
