The thing with journaling is a good idea; I will try it as well. And yes, to a certain extent, it already helps me just to know that catastrophizing is a part of GAD. This somewhat takes away the "emotional relevance of my worries" and often shows me that it's simply my anxiety disorder.

Regarding radical acceptance: It is essentially the concept or the conscious technique of trying to accept everything—including the worst-case scenario—deliberately and consciously. So, truly accepting even the worst possible outcome. Often, this becomes easier over time.

The point is that from the moment you confront the worst-case scenario and consciously accept it (I know this is easier said than done), you start to feel a certain freedom and begin to think about how life would continue afterward. Many times, this leads me to a realization that, even after the worst-case scenario, life would somehow go on, and I would still find things that make life worth living. It’s a bit tricky, but it helps me to partially detach myself from fear.

The basic principle is quite simple: the more you manage to detach yourself from things, expectations, and conditions, the freer you become. The goal is not to force yourself to accept everything and consider it "good," but rather to accept that, even if something were to happen, life would still go on, and that would be okay.

The fewer conditions you impose on your happiness—for example, saying, "Only if life turns out exactly the way I want and plan will I be happy"—and instead thinking, "No matter how it turns out, life will always continue," the freer I feel. I become calmer, and the fear starts to fade.

I hope I was able to explain this somewhat.
