First of all, know you aren't alone with being physically ABUSED... yes, abused, by your child. I have been verbally, emotionally abused, assaulted and my life threatened. All by my child.
It had taken me a long time to accept the fact that I was being abused by my own child. When you are left with marks or scars because of your children's actions, or you have things pulled out on you (like knives, hammers and scissors), and have your very LIFE IT'S SELF *threatened* and/or in jeopardy, that is constituted by law as ABUSE. Even if it's by a minor child.
As for medications (no matter the reason for taking them), if you have stopped them, YES, you have to let the doctor know. Tell them exactly why you did it. They have to know for various reasons. That goes for ANY doctors that have taken charge of taking care of your child medically! They base what is being taken as to if they can use other meds for other reasons as to ensure that there isn't any deadly mixings/cross medicatings.
If your child is getting so out of hand, no matter if just at home, both there and at school, or both of them AND within community settings (restaurants, the store, etc.), that behavior modifications (like a reward system and punishment system) are not working, then it MAY BE time to start thinking about ADD/ADHD (if they have it, too) medications and even Mood Stabilizers (like the Seroquel that B is on).
As for DENIAL that something is truly wrong with our kids, and the fact that they need more help than we can give on our own, we ALL go through it. Especially us moms of children such as ours. But also, you have to look at it from THEIR perspective, too.
Our kids do NOT want to be "bad" kids who are different in that view of them. All in all, they ARE *good* kids, but have brains that are hardwired completely different from their peers and from most other people in general.
Medications for the mentally unstable, for KIDS, has gotten SO many bad "reports". Mainly from those that have NEVER even tried them, and are unwilling to try them for their children as a part of their overall therapy.
True, not every child NEEDS to be medicated. But, most of the time, the ones that NEED it, don't get it, and the ones that DON'T need it, are the ones being "doped up".
In the end, the ONLY ones that can determine for certain that your child needs medications that will help with their mental issues is you, the doctor in charge of your child's care (Psychiatrist) and the child (more so their overall mental state).
Yes, I know that dealing with the agencies and doctors, and therapists CAN be a pain in the butt, in the end, it makes life SO much easier, when what SHOULD HAVE ALREADY been done IS being done.
Easier for them and their day-to-day life, and for US as their parents as well.
