Applications - Explaining Difficulties

I have come across the question of where I am asked to explain any deficiencies in my application (MCAT or transcript). In my 2nd year, I didn't do too well in organic chemistry. Part of it was my friend committed suicide, and the other part was me overestimating my abilities at the time (I had a really heavy course load). Do I mention both? I was obviously less mature then than I am now, so I wasn't sure if I should expand on that too. Thanks!
