what it seems it is not

Sometimes he seems so average that I will talk to him like I would anybody and he goes into meltdown mode simply because he either misunderstood me or he says he did not hear me. He claims not to have heard me but when I repeat it I have to repeat it word for word or he completely loses control. He must have heard something if he knowds to the word what I tried to say. i thought that he would be feeling better because he is finished with the yeast medicine, but he hasn't had a bm in 5 days, I know that is a lot of his problem these days, I am increasing his fluid, making him drink more water and juice and giving him the med. the Dr. prescribed for the problem. I am hoping he starts to feel better soon I miss the smiling happy little boy he was in April and May.
