i am an international student in sydney studying accounting. its against my will to leave my home country but i did because i was thinking of my sister and my mom and stepfather has no job. i work and study at the same time. in my first year i work at night 5 days a week and study in the morning then i started hearing from others that my sister is not going to school and has been having problems, coping on her own. i want to do everything so she would have a better life than me so that her experience will not be as cruel. i know i cant protect her from pain but at least i want to be there for her as no one had been there for me. now 2 years later i started losings focus because i am doing everything for her yet i wasn't there beside her when she needed me most. there's nothing i want more that to be at her side more than anything. i tried to held in the pain and home sickness silently crying inside, always smiling because they say when you smile your whole disposition will follow but every day it grows to a sickening level i could no longer contain. i just want to go home leave everything behind and embrace my sister and tell her i am here everything is going to be fine i will fight with you but leaving will mean disappointing the people that brought me this far. what should i do to avert the pain?
