A song about allergies

Should've stayed inside, you occupy my mind, the way you changed my weather

The moment that you cried was when I realized that nothing lasts forever

Should've stayed inside, but I needed some air. Oh, April I died, I didn't come prepared

Now I'm crying on my knees, I can see myself. I know, I know

That this wasn't meant to be, was it me or foolish hope? Or both?

The normal things I do, I hate them cause of you. You left a mark on me

I think of life before, before you reached my door. I breathed so easily

Should've stayed inside, but I needed some air. Oh, April I died, I didn't come prepared

And now I'm crying on my knees, I can see myself. I know, I know that this wasn't meant to be

Was it me or foolish hope? Or both?
