I'm glad to hear that you might have something to do. Was she talking to you as if you were a crazy person? Some people just don't understand. And if you are an adult, why do they have to tell your family? I don't understand that. But, at the end of the day, you'll be doing something for yourself. And if your mom doesn't like it, too bad. But if she tries to keep you from leaving to go there or something like that, that's a problem. I wouldn't know what to do then.

Are you on any Chinese social networking sites? You might be able to find people in the same situation as you, that would know where to go and what to do. It's definitely a very different situation to countries in the West, and somewhat to where I am: I understand about family, that's something really hard to deal with, but I don't know anything about services offered in China. I'm assuming lots of people think you should hide your problems and never talk about them, never draw attention, act perfectly and never bring dishonour to your family? It's tough.
And it's amazing how someone could see getting help possibly as dishonourable and a sign of weakness. Is that the case for you? I think doing things for yourself is good when it's not taken to extremes, and trying despite everyone putting you down and doing it on your own makes you a strong person. And working on feeling better and having things to do that are useful, that I think is honourable.
