Does an essay about mental health hurt or help chances??

I'm considering writing my personal statement about my struggles with severe depression and how I've gotten my life back together and improved my grades. I was also going to delve into how the grief of a loved one's passing affected it. But I've seen a ton of stuff online saying that an essay on mental health can hurt my chances of getting into schools. Some people claim the topic is overdone while others advise that colleges are likely to see you as collateral damage. I would consider another essay topic, but I'm worried if I don't talk about my mental health colleges will think my grades dipped for no reason when I had a genuine crisis. Should I change my topic?
