You trapped yourself and I couldn't save you

You dove so far down past that ground
Where red and blue I see
The bubbles stop arising
I didn't see another one for seconds to come
I jump in right after you
I push as hard as I can
How did you end up down here,
Your so far down, you freeze my hand and nothing and no one will let you in.

I guess it's your fault for this day
I guess I blame you for dying anyway
I'll never see your face again
On the long descension to the ocean floor
You gash a hole in my heart's core
