Flight on 9 August

I just found out that my flight to US will be on 9August morning so there is only little time left now for me to pack my things. Previously, I thought that I can still stay in Malaysia until 15August but now the flight has been made so early that I think I didn't ready to go yet.Very sad actually.Haven't pack anything.If any of you have any suggestion about what should I bring over there,please inform me.
