Mom4Hope, I hope the treatment plans work out for your daughter. My sibling had a lot of behavioral issues growing up, too. They had emotional outbursts, were aggressive at times, depressed and even suicidal. They was told they might have bipolar disorder. Turns out they had OCD, plus depression, and not sure if anything else. With treatment plus maturing as an adult they are pretty stable now and we have a good relationship. I cannot offer advice as to what is going on with your daughter, but I think it's great you are getting her help. She has a lot of neurodeveloping left to do, too, so I don't think anything is fixed yet such as her personality. I will also say my sibling's mental health affected me a fair amount growing up, and it might be something to consider with your other daughter, if she could use support as well. Like a therapist to process things perhaps.
