I think this song can be about how time passes by too fast.
This can mean that the band is splitting up, like others say, because of the rapid change of time. For example, the band first formed and made songs in their high-school years, so maybe school is causing them to separate after the summer.
But this song can be very confusing, like the phrases "There is simply nothing worse than knowing how it ends", "I will come back to life, but only for you", and "The world may call it a second chance but when I think back it was more of a relapse", though the last two seem to connect with each other.
But overall, all of these lyrics seem to be based on the quick passing of time.
