"J" with a certified.net address. You have sent several letters, and I am unable to write a personal reply (Yahoo returns them), nor post all of them because of the volume. My heart goes out to you. Your daughter is extremely troubled. She does need a great deal of intervention and help. It is possible that a medication could control her mood swings, but she really should be diagnosed by a psychiatrist in order to get the proper treatment she needs. There are myriad mental disorders that could be controlling her behavior, and a proper diagnosis is necessary. Please see a doctor in order to get some guidance in how to, or at least try to deal with her. Bottom line, however, is that some people will not get help because it's part of their illness. I hope that's not the case for her, or she will continue to tear this family apart. Get counseling now, please.
