There's bound to be highs and lows; necessary even, so we know the highs when we have them! Perseverance is the best thing of all. Sounds as though you've done well with that, so just keep going and it will turn right round again for you.

As to specifics, ask some of the folks who were there if they'd like to hear more from you or ask them how they felt it went last time. I wouldn't just take one person's word on whether they'd like to have you tell stories again; as you say, she might not have even been there.
