This song is about two people who spend the summer togeather and when its over one of them leaves and the one who stays tries to find themself again
the line "summer comes and leaves you with a fever that you caught when you were young" refers to summer being like a dream like if you think back to summers when you were young they dont feel real
"summer goes, makes you feel like life is real and hanging on for more" this is like when the pain hits them of losing the other person and all you want is them back and for summer to have never ended
then the person prays that there will be another summer they can spend with that person again
