YES! I seem to do it more when I have no special interest to focus on, like since July! I constantly had SOMETHING! Everything resolved itself or I realized I was being ridiculous. But each new symptom of something has me thinking, "NOW this is something real! THIS is the real deal!" then it goes away I laugh, a new symptom comes up and "Here it is! THIS is it" and the cycle goes on and on and on. Ever had two things at once? I had tonsil cancer AND colon cancer (the tonsil cancer went away, and I realized I was being a nut with the other one)
Then I thought I had pilomotor seizure disorder, only 20 people in the world have it and I thought I may be number 21!
Yesterday something weird happened to me and I said to my husband, "That's a symptom!" Then I paused and said, "Symptom of what, I don't know, but it's a 'symptom'" (I have to laugh at myself sometime or I'll go totally insane)
(I stopped googling so I wasn't going to look it up)
