This is EXACTLY why I am not telling my parents until I come back because I mentioned it before and my mom started crying telling me not to go and my dad said "you are crazy and selfish for going to a foreign country to do this"...I have told my BF and 1 cousin. My BF said I should tell my parents but I know my parents more than he does and it will only be DRAMA and NEGATIVITY towards me going and I don't need that from anyone...
I feel sorry for you and I TOTALLY understand your sentiments but NO ONE can live your life for you but you!!! Do what you think will make you happy....at the end of the day it is your life, your body, your happiness that resides in this so none really truly understands how you feel....Best of luck with whatever decision you make!!!
