Hazardously body

Somethings is really wrong with me. What I think now isn't what I speak. This is really bad. Like recently, whenever I wanted to order a plain rice with some side dishes, then I told the guy I want I want to have fried rice. It's a totally different food and I will regret it that much after I order. I have no idea what is going on right now. My mind is so empty that I will wander around so much and do nothing. Maybe this is due to my migraine again. Hurting for more than two days and there is nothing I can do nothing for it. 

Can anybody help me?
