Undergraduate / Would it be a bad idea to use this topic for Common App Essay #1 or #5? [7]

I was thinking about writing about how I was secretly ridiculed by friends and classmates because of my appearance during 7th-9th grades and how it prompted me to basically include everyone, treat everyone with kindness, like a friend, etc. or does that have a huge potential to turn into a boring essay topic? I was never physically tormented by my peers, just verbally or in the case of my "friends", behind my back. I have come out of the situation a stronger person but I don't know if this is a heavily overused topic or one that would require an extreme amount of effort to capture attention from admissions officers or even one that could suggest that I'm using the "woe is me" card? Someone I asked said it would sound incredibly immature. After he said that, I went back and read what I had so far and figured that it did kind of sound like how he said. I would like more feedback though and possible suggestions for a better topic to write about for either essay #1 or #5.

Thanks.
