Also- I would suggest digging deep into how funding works in your jurisdiction and state. This might take online searching of link after link- forms and stuff that you think apply only to those working in the system can sometimes be very informative. You might not need this yet, but I am suggesting it because I found that here, once a child is under the control of one agency- such as Department of Juvenile Justice- you cannot get them help from another agency without going thru (and getting approval from) the agency the kid is already involved in.
It is my understanding that in some places, Department of Juvenile Justice can be a great way to get necessary help for a child. In ours, it is not. I have met two other families with kids about my age and involved in our Department of Juvenile Justice, while I'm sitting waiting to visit my son. One family said they had to jump thru all kinds of hoops for 2 years and now their son is going to Residential Treatment Center (RTC). My son is going to sate Department of Juvenile Justice, then we'll be jumping thru hoops or he'll be turned over to dss- actually- I'll have to jump thru hoops while he's in there, too. The family I met today- well, her son did the EXACT same thing is mine, is the same age and also has an axis 1 diagnosis. The Mom has been trying to get Residential Treatment Center (RTC) for her son. They go to court in April- she is about to lose her son and he is probably going to be a ward of the state.
The funding issue is because the funding that Department of Juvenile Justice has access to does not fund mental health treatment for axis 1 diagnosis's. If your kid needs this and is involved in the Department of Juvenile Justice system, it is a nightmare to get those in charge to see what is needed, jump thru hoops while they try all their crime prevention methods, then get them to "cross over" and try to access help from other agencies for you and your child.
I obviously cannot tell you what works- only what didn't work for us. But from my standpoint, I think you have a Special Education issue and would contact a Special Education attny first if I were you. But again, what I tried did not work for my son.
Giving what I know now, I'd also advise checking to see of GAL's in your area are attny's that have NO experience with mental health issues or if they are warrior parents. This could help you decide what to ask for. One of the reasons my son's gal blamed me for difficult child's problems was because she said he wasn't "cured" yet. I found that here, a GAL has to be ready to get a license as an attny and get 6-7 hours of special training- this is for 8 subject areas and only 1 of those has to do with advocating for mental health- so I don't think they quite "get" the idea of what is needed and wouldn't dare ask for help from our Department of Juvenile Justice again.
Anxiety: I can honestly say that I think my son's BiPolar (BP) diagnosis is not correct, or at least is a minor case, now. His chaotic behavior is a result of anxiety and depression, I honestly believe. His latest psychiatrist in in=patient care changed his diagnosis to Mood Disorder not otherwise specified. If you can get someone to help you deal with the sd and get Department of Juvenile Justice to allow transfer to the mental health dept, I think you'll be a lot better off. Early on, I tried to keep Department of Juvenile Justice involved in the sense of overseeing things thru probation while I got mental health for difficult child. In hindsight, this was a HUGE mistake. But, our mental health dept HOOVERS (except the crisis center portion) and takes 1/2 day for a 1 hour scheduled appointment, which nearly cost me a job. They lost difficult child's file for weeks and after 3 mos. threw their arms up in the air and said they didn't know what to do, so they aren't very high on my "have faith in" list. This is why I didn't push for transfer to their dept. I'm bringing all this up to let you know how things can differ so much, depending on how the system in your jurisdiction works.
If there is any way to meet other parents with similar issues in your exact locality, I would strongly suggest that, too.
