Yep, while this is awful, you caught it early and can get her in to see someone right away. Because you don't want to try to fix this by watching her yourself -- you know that won't work, right? Sounds as though she's having a lot of trouble adjusting to things like her father's death and the neighbors and all the rest. A good therapist can help a lot, and you know that it's better to work on things as soon as you can, rather than waiting years to do it.

Good luck.
