I'm no help on the specifics of depression, but it would seem that if she's threatening self harm, even just in the heat of the moment, you should into see someone for a workup much more quickly than a few months. No matter what, you need an accurate picture of what she's dealing with so that you can respond appropriately and be armed with knowing what to look for if things continue to spiral out of control.

While you're squaring that away, DD's neuropsych has me track DD's moods on moodtracker.com. I don't like storing that kind of info online, so I signed up, saw what it had you track, and I just started my own notepad.

Growing up is such hard work.
