This is Markdown, like Reddit. There is an easy fix, and you don’t need bullets (though that did the job in a pinch, good thinking). Check it out:

If you put two spaces after every line before the line break, they will display as separate lines.
Without the spaces, the line breaks don’t matter and you end up with a big paragraph.
I usually do four spaces just because, but two spaces should do the job.
Try it.
