depression
"For ME it was awful.  I was on this pill for 7 days.  I went to the doctor today because my heart was beating so fast on these pills and I was paranoid, anxious, shaking, and very very Bit**y.  I thought I was having a heart attack at work I was crying, it was awful. I went to the doctor and I couldn't get words out.  My pulse was 115 and blood pressure was high (never ever is) it just shot up. The doctor said I was having a panic attack and that it is due to the medication.  She took me off it and for the next 5 days I am on LORAZEPAM 0.5MG (sedative to calm me down - take it at night) and switching me back to sertaline.  This was the worst experience of my life.  I thought I was going to end up in the ER or dead."
