Thanks all.

She says she didn't plan to do it there, she had been thinking about it but it was a spur of the moment thing.

Doctors have know said they think the problem is less to do with depression and more to do with her personality disorder. They believe she is doing this to try and manipulate the family into doing what she wants (supporting her financially). They have taken her off all meds as say they weren't helping and only gave her ammo to do this again. They say she is beyond their level of expertise and have referred her on to a specialist in personality disorders.

Feeling pretty lost.
