Hello Friend, Good that your seeking a help here. It's good that you fairly understood your problem well. Anxiety is the root cause for the sleeplessness. As body and mind are interlinked, this emotional disturbance influence your body with symptoms like sleeplessness, nervousness, poor appetite, constipation etc. In Ayurveda, it called as an effect of imbalanced air energy or Vata.
