You don't know my name

In reality my name is Christina.
Back in the day my name was full of smiles.
Then suddenly it changed to everything's wrong.
Yesterday my name was giving up.
My name was once feeling guilty.
Today my name is hopeful.
Maybe tomorrow my name will be happy.
Inside my name is always worried.
Secretly my name is simply scared.
In my dream my name was everything's right.
Hopefully in the future my name will be loving life.
