Hello, I am 18 years old girl. I appeared for competitive exams 2 months ago. During that period, I used to sleep at 3 or 4 am. I also lost somebody loving to me 2 months ago. Since then, I was suffering from anxiety. I also have strong acidity, indigestion, pain in left arm, sore throat and cold. I feel full after small meals. My stomach becomes bloated. What could be the reason for all this? Please suggest some remedies.
