Puberty has EVERYTHING to do with it. The teen I am a caregiver for was doing just fine, some would say "normal" child even though she has early years issues from bio parents. Adopted and doing fine until puberty. Now she is violent, ODD, self harming, abusive to animals and adults who try to stop her. She has turned our home into a jail of daily abuse. She refuses to work with a counselor that is top in her field. She has become very self serving, non sympathetic to anyone even if injured or very sick. She acts out at a drop of a hat. She is now 17 and we are counting the days. 410 left. We have called every service available and she refuses to work with any of them even in home services. The police wont deal with her or even arrest her for breaking up the house or breaking bones of adults. HANG ON! It can be a very long vicious ride, and in Maine with no outside help without the severe mental illnesses being diagnosed. ODD means nothing in Maine.
