I\'m not her

Working hard,
To meet your expectations,
Needing your approval,
I need your support, not your judgment,
I feel like giving up,
The first year of High School,
by surprise, a teacher did not compare me to her,
I work hard,
Get good grades,
when I tell you to stop comparing me to her,
You say you don't,
A minuses aren't good enough,
You say I'm not trying,
You say people compared you to your siblings,
You were just compared on how you acted,
You compare us on everything,
but I'm not her
