I copied it from Facebook. Is there a way to edit it once posted?

use the space bar between sentences or various parts to make paragraphs or at least add extra spacing.

Don't think there is after actually posting, unless an Admin would assist in doing so.

Otherwise, there is a feature in FireFox called "Reader View" which opens up a new window with larger text and wider spaces between the lines ... very useful feature for text such as this.
(for anyone using a current version of FireFox, the "Reader View" is a small 'open-book' icon in the address field)
