All of the above is good------ I also wanted to add that we can help our children understand their emotions and deal with them better. If any type of seizure disorder is ruled out, then I would begin working with her when she is NOT upset by talking about emotions and the way she feels. Give her words and language to use for different emotions. Ask her questions about what makes her mad? What makes her sad? What makes her frustrated? What makes her happy? What makes her excited? Get a good dialogue going with her. Then talk about when she starts to feel mad, what can she do? Give her ideas at this point and there are many go to things a person can do when upset. She's in second grade----- I have a second grader too. Her teacher could take a poster board and color hands on it and then hang it on the wall and tell the class, these are the helping hands. If someone is mad, they can go to the 'helping hands" and push against them to help them feel better. That pushing action is very soothing to the nervous system. Kids can give themselves a tight hug and that deep pressure squeeze is calming to the nervous system. Her teacher could have a 'go to' spot that is the calm down spot. It could be in the corner and be a bean bag chair. The teacher could even put a cd/tape player and headphones by it and a child can sit there with the headphones on and self calm. You can help her with a dialogue she can use in her head to 'self talk"----- "it is okay to be mad. breath in and out. it will be okay". All of the self calming techniques can be taught and could be her go to things when she feels herself getting upset. And that is the key. If she can identify herself that she is getting upset, she can then do appropriate things to calm herself down and handle the situation.
Has the school suggested that she be evaluated for intervention at all?
And there are free clinics ...most cities have them if you google free healthcare for child or free clinic you will find one and as the previous poster said no ER will turn a child away ..so there is help out there.May I ask has anything new happened in her life, how is home life , has she siblings ..she sounds upset by something .Has there been any divorces,significant changes ?
You really need to have her seen by a doctor as soon as possible. There are certain kinds of seizure and/or neurological disorders that present like this, and if not medically based, then she needs to be seen by a good mental health team. Most major children's hospitals will see children without health insurance - I would bring her to the ER after her next tantrum/episode. It would also help the doctors if you could get a tantrum/episode on videotape. Her school may also know of a local clinic that will see children without insurance. Good luck
