Anxiety
"I was in England when I started getting feeling of depersonalization, forehead pressure, fear, negative thoughts and irritation etc. I came back to my country and consulted a doctor. He diagnosed me with Generalized Anxiety Disorder. What he prescribed me may have worked but honestly speaking I did not give fair chance to the prescribed medicine.  He did not prescribe me Xanax but I managed to get it from somewhere myself as I had read about its effectiveness against anxiety. It worked perfectly for me. I killed my anxiety with it. It normalizes me and keeps me going ahead in life. I give 9/10. "
