Saw your post at siuyau.com. Just wondering how old are you?
Personally, I should not say anything bad since you are already in a complicated situation, but.... I think you are quite immature!!!
I did have a similar situation as you- leave HK, study in somewhere else... learning other language, adopting different culture and parents aren't here...
Come on, life is still passing on... You are not the only guy who suffer in this kind of situation.
The main point is you are not doing your best to satisfy your own life and just keep blaming and blaming your parents, your friends or whoever...
If you can't change your situation, what you can do is change yourself to adopt it... and overcome it.
One good french expression for you " C'est la vie!"
I won't come back to this site so you don't have to reply me, take care. See you somewhere in siuyau.com
Take care man.
