Hi, and thank you for your multiple insightful comments! Of course, you can have your own definition of what constitutes a need vs. a desire. But for Epicurus, desires clearly come in three types:

1. Natural and necessary desires: not satisfying them will cause, according to him, “pain in the body.” This seems to be what you call a need in your comment above.
2. Natural desires that are not necessary, that is, they would not cause pain if not satisfied. This would be things like friendship, or perhaps sex. Not having these things would cause you some discomfort, or some “trouble in the soul” (Epicurus’ words), but not physical pain.
3. Vain desires. These are due to “illusory opinion” (Epicurus), and lead to no pain and no bad feelings when they are not satisfied. These seem to correspond to what you label “desire” in your comment.

When I used the word “need,” I used it in Epicurus sense of a natural desire (whether necessary or not). See more about this distinction in my separate article here: https://daily-philosophy.com/daily-seeds/epicurus-on-desires/ (also on Medium, but I don’t have the link now).

Many thanks for your comment and greetings!
