Having paragraphs as a standard is quite bad, as a paragraph can be just a single sentence or something absurd like a thousands words. In any case, word count should mark the standard, but then people will bitch about quantity versus quality.

All paragraphs have three parts: topic sentence, supporting sentences, and sometimes also concluding sentences (,mostly in academic works). The [i]topic sentence[/i] states the main idea of the paragraph. It limits the topic to one specific area that can be discussed completely in the space of a single paragraph—this is also called [i]controlling idea[/i]. For example: Gold (topic) is prized for two important characteristics (controlling idea). This would be the first sentence of a paragraph discussing why Gold is prized metal, and its [i]supporting sentences[/i] explains or prove the two important characteristics.

What people tend to do is that they break new paragraphs for no particular reason. I noticed the same mistake in your post, but that's alright. From your post, the first paragraph should have been this:

[i]Blair lay on a bed within the Motel 6, she never motels, it's like home to hookers and business men looking for a good time with them. [...] It was on the news and talking about the overcrowded hospitals and then an influenza spreading after Black Friday, Blair then realized that things were going crazy and these days could be the last of mankind.[/i]

And the second should have started with this:

[i]Her phone rang and she answered it, "Hello?", then a man's voice was on the line and said, "Confirm your identity." [...] she gone to Google Maps and saw the waypoint, it was nearby her and she ran towards the waypoint.[/i]

In a nutshell, a paragraph should entail things related to a single idea, and when that idea has been discussed, you move on to the next paragraph no matter how long or short your first paragraph was!
