When to breathe

I'm learning this song "Close Every Door" right now. It barely has any rests which I think means I have to breathe sometimes where there is no rest. I should I breathe where the long notes ae right?

Great song! Since long notes are often the end of a phrase, right after a long note may be a good place to breathe. Choose breaths where there's a natural pause in the phrase (if you were speaking the text). Anywhere there could be a period, comma, semicolon, etc - that's a good spot to breathe! You also want to consider the musical line and try to not break up musical phrases that have momentum. Let your ear and musical sensibility help guide you!

Thank you!
