What kind of disorder is this?

ever since november to december, my aunt moved to a new house in taiwan and right then she began having emotional and psychological problems...she's on anti-depressants now and can't go to sleep without them..my family is very worried b/c this has happened so suddenly and my dad does not believe she is depressed but that someone is controlling her..we just talked to her on the phone yesterday night..she is usually very strong and assertive however her attitude is now completely opposite...i was a little afraid talking to her..she sounded very passive, scared,and weak...i panicked when the middle of a few words she suddenly said goodbye...but just last week she was a little stronger, and said she really wants to make an effort to get better but she somehow feels like she can't..and this week she worsened. she was frantic on her first sentence to my mom, said she's terrified bc she
This sounds a good bit like an adjustment disorder with mixed emotional features. Her symptoms of anxiety mixed with depression (and possibly some paranoia) are becoming severe. Her medication clearly is NOT working. It is important that your aunt contact her psychiatrist to let him/her know that the medication is not effective. A dosage adjustment and/or medication change is likely in order.

It could be her medicine..she needs to talk toa a doctor or therapist. This sounds like a strange case to me, but if you ask me I would ask her to come and live with you, if thats possible. It sounds like shes in a time of great need, so be supportive and stay aware of whats going on.

It can be a lot of things. First comes to mind depression over anxiety disorder or OCD, or the opposite anxiety disorder over depression. You say it started when she moved to Taiwan. It's possible that she started to feel lonely and it started some kind of depression. My anxiety disorder started when I first went to a holiday without my family.You're talking about insanity but insanity is something totally different. "Insane" people do not try to get better because they can't know there is something wrong with them. Your aunt has a psychological "disorder". Be as supportive as patient as you can. Both you and your family.
It's severe depression, perhaps with psychotic features (paranoia), or at least that what your description sounds like to me. Moving may have triggered or made it worse. In any case, her antidepressant is not the problem. The problem as far as the antidepressant goes is that it is not working. She or her husband need to call her psychiatrist and get her in for an appt. No one on the Internet can say what's going on with any certainty.
