Mixed feelings.
Anxiety can of course be debilitating. We are told to empathise with people with mental illness. We are told to do what makes us comfortable.
On the other hand, speaking from experience, sometimes it’s in our best interest to push ourselves, even if it’s very unpleasant.
I used to have extreme anxiety, which is not now not as bad as it once was as I have worked hard to stretch my comfort zone. I would fake illness to get out of speaking in front of the class at school, and if I’d somehow been strong armed into it I’d have broken down and cried. As an adult, I have tried to combat my public speaking fear. I’d lose my appetite weeks in advance, it makes me feel physically sick, my voice shakes, my legs tremble, I sweat like crazy, and my mind goes blank. However, by making sure I have extremely thorough notes on my laptop in front of me, I can get through it.
Now, I still get pretty bad anxiety symptoms during and just before public speaking but at least I have techniques to get through it and I’m not consumed by anxiety weeks in advance. Fortunately I very rarely have to speak in public but I know that if it came to it I could probably get through it.
People need to face their fears most of the time, I’d say. There might be a minority of cases where facing their fear could worsen the trauma, but I doubt this is the case with your colleague.
