Help with common app essay introduction?

I want to write my college about how i’ve been struggling with eczema for my whole life, and how it’s helped me grow stronger and shaped who I am as a person. For those of you who don’t know, eczema is a skin condition that causes inflammation, rashes, and severe dry skin. I’m having trouble coming up with a good hook/introduction. Does anyone have any ideas and are willing to share with me?

maybe think of a hook with a lot of imagery?
