Hi there. I just dropped home and checked the site and I wanted to welcome you, although I'm sorry you have to be here. Trust me, you are NOT alone.
I have some questions that may help us be able to help you better.
1/Has she always been this way? Has she ever been evaluated by a neuropsychologist? How did you get the diagnosis and what tests were given to her to conclude she has the diagnosis? While there are NO blood tests, there IS testing that can be done that can sort of direct the professional to one or another disorder. in my opinion NeuroPsychs do this the best--they tested my son for ten hours.
2/What medications is she on and has she been on? Did they make her worse? Has she tried any mood stabilizers (Depakote, Lithium, Lamictal, Tegretal, Trileptal). Has she been tried on stimulants and antidepressants and, if so, did they seem to make her even angrier and worse? Could she be dabbling with drugs/alcohol?
3/How was her early development as far as speech, eye contact, cuddling, milestones, ability to relate to others her own age as time went by? Does she know how to have a give and take conversation that requires abstract thinking? How are her grades? Does she have an IEP?
4/Are there any psychiatric problems or substance abuse issues in her family genetic background, including her absent biological father. Unfortunately, she does have half his genes...he could have passed something along even while not being there. Are you raising her alone?
You may want to do a signature like I did on the bottom of you page to give us all a quick overview of your situation.
This is a great group. The more you tell us, the more suggestions we can make. It sounds like she has some serious problems/disorders that either haven't responded to the treatment or perhaps she hasn't gotten the right treatment or diagnosis, which often happens too.
