Small Things - JoJo

I found your shirt, cleaning my apartment and I made it worse
And I swear you couldn't even see the hurt, I swallowed hard
And when my friends think I'm going through it
I say I'm great now, but the truth is

[...]

I heard your name just as I was heading home the other day
And I swear, I couldn't even sit up straight, I swallowed hard

Snippet 2
I’m getting good at holding it in
All my emotions, all my feelings
But the more that I fight them, the bigger they seem
What really kills me is all the small things
