I had acidity issue due to which i could not sleep for many nights. Now I have developed a fear that i shall not be able to sleep at all. when the night comes i become terrified, that perhaps i might not sleep. previously I used to sleep before 10pm and wake up at 4am, but since my acidity i have developed this fear which has also ruined my quality of life. My mother is parkinson patient for last 20 years, sometimes I also get the fear that I might have developed parkinson whenever i get slight trembling of my hand due to confusion or fear mostly, although my friends and colleagues say hat it is normal.
