I think chapters tend to get down and out about recruitment / service projects / fundraising / etc. because they feel like it's "work" and not fun.
Having events that not only are more upbeat and fun, but also help build unity among the sorority (ie team building activities) will help bring the morale back up in the chapter.
What's that line, "all work and no play makes Jack a dull boy..." haha!
