I've run into the same rut with personalities/gossip before. What helped me was to mix up my meetings a bit and try some I hadnt been to before to hear the message from different faces. It meant a longer car ride at times. However, I found it very beneficial to get away from the "crap" for awhile. I went back to those original meeetings and I seemed to have a fresher, healthier perspective on the "ol'" people I had seen day in and day out.
I wish you the best.
