A Couple Of Nights Ago, I Had An Episode Where

A couple of nights ago, I had an episode where my mind raced from one topic to another, to the point I couldn't maintain focus on a subject long enough to describe to my wife what I was even thinking of. I got sick to my stomach, and was afraid I was going to vomit. As I got up to get out of bed, I felt like I was going to pass out, so I lay back down on the bed. I ended up laying there, as the feeling passed, but I had fight or flight sweats. Since then, I have had instances where I have lost track of my thought processes - frequently during the day. Blood pressure is normal, physical health has been very good.
