I am an engg student.i don't know what is my problem . One time I had a chest tightness feeling .that time I was very afraid..but when I see doctor they said there is chest infection...but I was very much afraid...from that day onwards my life changed..I was afraid of everything.i was afraid to eat..I feel like it will stuck in my throat...I ate liquid foods.recently my father died..I feel very sad when I wake up morning that there is nobody for me...
