I just want them to know 
That I gave my all, did my best 
Brought someone some happiness 
Left this world a little better just because 
I was here 

I was here, I lived, I loved, I was here 
I did, I've done, everything that I wanted 
And it was more than I thought it would be 
I wanna leave my mark so everyone will know 

I was here.
