mance anxiety
"I thought I was going to have to drop out of college because I was completely unable to do any kind of presentation in front of the class.  I actually am very social and have no other kind of anxiety, but when it came time for me to do a presentation, I couldn't talk, my hands were shaking, my heart was going to race out of my chest, and I was sweating heavily. I literally ran out of the classroom and stayed in the bathroom the whole time.  I tried again and again and failed each time I tried to present.  The anxiety was AWFUL.  I went to my PCP and asked her about Propanolol (I'd been researching possible meds) and she had no problem prescribing it.  I've had two presentations this week and I did them like a boss!  This is a wonder drug!"
