Hello dear, from your description it seems you are having anxiety symptoms and insomnia. It may be due to underlying stress and/or some depressive or anxiety disorder. However your mention of staying out of India, is not clear as to whether it is a cause of your symptom or effect(solution) to them. Kindly seek psychiatric help at the earliest, so you may come out of this condition and lead a productive life. Hoping this helps you in some way.
