I did mention the Nocebo effect.

And I do think talking to others or having professional help to a normal psychologist is absolutely okay, the right thing / a good thing.

Yes, my last point was meant generally (can't edit anymore). Ie. we often tend to try to convince others with long-winded arguments, while what may be needed is just listening and learning different perspectives. It rarely works well that you can actually "convert" people. When that succeeds, the ground for critical thinking tend to get even worse, ie. in closed or cult-like groups!

More important than the positions we take, is the critical introspective thinking that leads us to along the way (free thinking).

I've even heard of a study that showed that stress is only bad for you if you believe that stress is bad for you.

That's an interesting one to ponder, isn't it?
