sorry for what you're going through...you've spoken about your daughter's counseling appointments. What does the counselor say? Sorry, but this behavior doesn't really sound like depression, especially when you add in the insane stepmother. What grown person brings their stepmother to a hearing???
Please investigate information on personality disorders and discuss them with your counselor. I hate to say this fits a very sad and sick pattern. If you are dealing with something of this nature, or even something like depression, DB really has its limitations. Still you've received some good advice about detachment. But it's not really so simple when you're managing this kind of rampant instability.
