That's called ADHD, I have it and yes it's a pain at times, if your condition is extreme you should get medication, a therapist would help. It doesn't have anything to do with the horoscope, I am a Pisces.
C'mon people this has nothing to do with the zodiac I'm a gemini too and that has never happened to me.
It's obviously a disease, go and see the doc, you need some meds, it may get worse with the years if you don't act with time.
