An ill and distracted flight attendant failed to detach the B737 L1 girt bar and realized the error ...

Narrative:

I was the 'a' flight attendant and was feeling nauseous and dizzy during decent. When I reached down to disarm the L1 door I must have disengaged the girt bar and instead of attaching it above to disarm; I rearmed it. I attempted to open L1 door along with the agent; when I realized the door was still armed. We closed and I disarmed the door; but the slide pack had dropped into a position that prevented us from opening the door. Maintenance had to be called to remove the slide pack. We deplaned. I believe that I am experiencing symptoms of a sinus infection. The dizzy; nauseous sensations I was having contributed to a potentially deadly mistake. Even though I cross checked myself; had the red flag up; and made my announcement I will always be conscious of how the door feels and aware of the dragging sound the slide makes when the door has not been disarmed and you attempt to open it. That final awareness saved me from one of my worst fears.
