Welcome back @cryptocopus. Some steemians were going to send out a search party for you! To answer your question, I think the point you made about what drives a person is important to get out of a funk. If the reasons that were pushing you to write 5 posts are no longer there, or maybe your focus has shifted, so it's best to do the following;
- Identify what has changed and why
- Accept that not all changes are negative so maybe your feelings of feeling demotivated are redirecting you to a more purposeful path/project
- Channel your focus and energy onto what you feel will be the most rewarding to you
That's how I normally do it. If the funk is a temporary, I usually stop, focus my energy on something entirely new then revisit to see if or how my feelings have changed. Hope that makes sense.
