"I needed a way to compensate for my low self-worth. So I decided that I'd be perfect.

I became a perfect daughter, perfect student, perfect in my work. And got into perfect positions.

It is a good thing to work hard for what you want. But if you're fuelled by insecurity and self-hate, you end up growing a black hole in your chest.

No matter how hard you try, it's never enough. Slowly, the black hole starts to swallow you - the way a python digests its prey - until one day, you wake up wondering why there's none of you left."
