All of them apply at one level or another, but I think the big one for me right now is allowing myself to feel the emotions. Harder than it sounds, but I noticed just this week that if I can manage to 'feel' when I start getting anxious instead of telling myself that I'm okay and I have no reason to be upset, that the anxiety dissipates. Learning to do that is definitely work. It takes a good amount of focus not to fall into the old pattern.
