Oh, man. This is a very touchy issue…
Don’t want to go into it right now, but I have some very personal experiences in dealing with this kind of dilemma. The enemy is this perception that any admittance to having a mental problem is starting on a slippery slope that can only end in a sanitorium. There is also a very negative prejudice against any medication that affects the mind, including sleep aids. I know my mother gives me shit for taking Ambien to overcome jetlag.
I don’t really know what advice to give you, since I have had nothing but frustration in trying to get this person the help. Except perhaps this – your friendship is important to her. Don’t jeopardize that in trying to pressure your friend into doing something she’s not ready for.
I am really hoping that there can be a sea-change on a society level in attitude towards mental illness soon. Taiwan is still a very reactionary society in many ways, but I believe that positive change will come with time.
