Help me find this super obscure song?

So it was probably like 2008-2010 when I found this song (probably like on eSnips) and I remember VERY little of it. Praying someone has heard it and can understand my insanity while I describe it.

It's a woman singing it. Her vocal pitch is very coloratura soprano.

The base instrument is piano.

The melody is da dat da da da, da dat da da da, da dat(different keys, same chord) da da da. Yes, impossibly vague 😭

These are the pieces of verse lyrics I remember (--- are missing words I can't work out):

When you look in the mirror ----

---- inside

When you're clenching your fist ----

---- the reason you fight

It was a very uplifting song, very much a "theres a reason for your suffering' kinda hopeful song.

My brain is telling me the artists name started with a 'Ch' or just 'C'
