Did they release her with meds? Sounds like she needs some. I can relate to yelling at my kids with out reason- sure have done that! If she is on meds she may need something else or different. I am a clinical psych major and I can tell you that treating mental health is so different than treating physical illness. If someone is diabetic- there is a blood test to confirm it and insulin to treat it- done. In the field of psychological health there are no tests that tell a Dr exactly whats wrong; there's no one med that will fix it all for everyone. Its just trial and error. Try to be encouraging to your daughter but a little tough love may be in order- sometimes when your BP you really dont wanna do ANYTHING but its not healthy. It might do her some good if you give her a small list of chores and let her know your EXPECT at least that minimal assistance from her while she and her children are living with you.
