What should I do?
In line with the guidelines I'm offering, I'd suggest adding a similar summary like you had above to the module documentation, plus a note that you're not actively maintaining it and are looking for a co-maintainer to hand off to. That way, any prospective users are at least aware ahead of time what to expect. Plus, you'll keep your request for help with it out in front of the module users.
