Is this acceptable for college essays?

My daughter’s best essay last year (and she had many-with no help from me, re topic, or even editing) was about how she overcame a challenge…as related to her brother, who is a recovering opiate addict. To be honest, I would have never in a million years suggested that: Why, it may end up all about him, seem like a ‘woe is me’ story; or appear to be more cathartic than enlightening! But none of those were the case. In hindsight I believe that since it was such an emotional, pivotal time in her life-she was able to put forth some incredibly insightful and powerful thoughts. So I get your posing the initial question, @collegemom2000 - and I get that it came back to her brother.
