we upset because we are jealous
we jealous because we feel insecure
we feel insecure because too many questions mark in our head
then we guessing, fill up our head with plenty negative things, suddenly we afraid loosing you
we afraid loosing you because we love you
sounds stupid, yes..
but believe me that feeling is not easy to handle...
If you care to her,
tell her how do you feel..
don't let her stay in question mark..
having those kind of feeling is hurting and torturing..
