Why is it so hard?

what is right and what is wrong..i don't seem to know how to differentiate it...we often made mistake because of we always think what we do is right..i don't know if i made this decision this time round in my relationship is working and i've got this funny feeling saying that it's nonsense...first impression of ppl towards me is i'm a party-animal,have many boyfriends,wild, and all..but actually i'm nottt....am i?looking strong on the outside but i think inside of me i'm actually fragile...get hurt easily..not physically,i mean...this whole feeling is just weighing me..i don't feel like it's gonna work but i really don't want to look back one day thinking what could have been...that's why i opt to try...i'm seriously not good in this man... :( tell me what to do.....wished GOD has a hotline in heaven so he would tell me if he's the one for me...or telling me what to do is good enough!
