When I experienced someone like this for the first time… my eyes opened. This person’s ability to takeover, frustrate, exhaust, and actually distress an entire room was really quite astonishing!
If you haven’t met someone like this, believe me, they exist.
After weeks of this, it became apparent they were not being disruptive because they were selfish or rude, but they had very real long standing anxiety issues and needed attention and reassurance to emotionally regulate themselves. Things were very tough for them at home. They were receiving therapy, but obviously a multi pronged approach was needed.
Ultimately, what worked, was a mutual understanding the rest of us had to listen to them at length, without interrupting, and smile and nod, as appropriate. Roughly half an hour daily. Just let them talk themselves out, then give reassuring feedback. Basically a figurative pat on the / tap on the back.
What I am describing here is office parenting. The work place shouldn’t be the place for this… but where are whole people and cannot always compartmentalise and we have a small responsibility for the well-being of those who work for us.
This person is doing much better now, we have managed the situation. They just needed to feel accepted into the group and cared for and seen and heard and that their opinions and needs are important. Once this was made clear to them, with verbal praise and sometimes little tiny rewards, it was all meaningful and it has healed/cured the ailment.
Good luck, I know it’s emotionally draining and extremely frustrating. You can manage this!
