So this has great bones and a chance to be really great.
Trust me, descriptive writing in only so many characters isn’t easy. What you can do that I noticed is something like in the sentence where you said “I begged my mom to put me in cheerleading and ballet and tennis and basketball” an improvement would be something like “I begged my mom time and time again to be in anything; Cheerleading, ballet, tennis, and basketball but she said I was too cool to blend in the crowd, but that’s all I ever wanted.” Then you can also nix the first sentence. But that’s just something nit picky.
keep working on descriptive writing. For sure touch on emotions instead of telling the readers, let them feel what they feel.
Infinity.
