Like this? If this is good, I can give you the song names in order:
Sometimes I don't wanna be happy
Some days, things just take way too much of my energy
I just wanna have a good day
Ain't got no tears left to cry

When I hear your voice, I know I'm finally free
And you're right here by my side
All i have is myself at the end of the day
They can't steal the love you're born to find
