Hi, If someone could please tell me what mistakes I'm making using past perfect properly in this past-tense first person narrative, I would appreciate it so much.
I had met Jill nearly twelve years earlier when I had been pushed into a foam tumbling pit on my first day of gymnastics class. While I struggled to get out, crying, she grabbed my hands and attempted to lift me out, but despite digging in her heels and pulling with all her might, eventually fell to join me in the pit. We spent the rest of the class burrowing tunnels in the foam blocks and talking about how mean our instructor was. Ally had joined our class the next week, and the three of us had been best friends ever since, although the dynamic between Ally and Jill could often be slightly less than friendly.
What do I need to change in order to use past perfect correctly and make this paragraph grammatically correct? Thank you to anyone who can help!

PS- Do I need a "she" before "eventually"??
Anything else grammatically incorrect/clunky with this paragraph?
Thank You!!
