Narrative Passage

Here is a passage from my Personal Narrative.

Before the creation of the Equestrian Artistry club, I was unsure, and thought that i was the only one who excessively drew horses excessively. Before the construction of the club my life was as lame as an unsound horse. Before the clubs formation the constant nervousness of guarding my drawings made it feel like a horse continuously cribbing on my brain. Prior to horse club being in my life I felt like a mere pony among stallions as I walked down the hallways, knowing that I was equipped with loads of horse drawings in my backpack. Then I realized that I had other schoolmates who shared the same passion for equestrian art.

I think this passage needs some work cause I am not sure if some losers will be able to understand all the horse terminology. And I think i need to finds words to replace before because i use that word a lot.
