Melt Downs vs. Anxiety Attacks???

Our psychologist wants me to document these times when J is either "melting down" or having a "panic attack". Often difficult to do as I am doing one or the other or both myself. Truly, it is a difficult task because a melt down often leads to anxiety that is true and genuine. A meltdown might start as oppostion but that opposition is triggered by fear or anxiety that which even the child does not know the cause. So we discipline, we take away DS or he loses the dollar he was trying to earn (we have only been up for half an hour) but soon, this becomes more of fully on panic. Panic of what? School? Accidents? Separation from me? All of the what ifs that are going through his mind?  Tuesday he lost his dollar because he was ugly. He aggressive and said NO. He would not brush his teeth. He did not seem anxious. The rest of the week has been anxious, tearful, and heartbreaking but he made it and went to school each day earning his dollar.
