Agoraphobia on tv programmes . It's almost always shown as something a character has at a very high level. Often it's a character that hasn't been out of their flat/house for a long period of time, i.e years.
It's all about dramatic effect. The truth be damned.
The truth being that it isn't always that severe . Sometimes you can get out of the house, but you get really anxious of being in unfamiliar places on your own. The fear being you'll get lost and trapped. You can out of your flat/house on your own but stick to a very small , and safe, area that you know.
