Thanks from me as well. 
It's very true that sometimes distractions and hobbies don't work 'cause we are still monitoring symptoms all the time. I guess we don't have to expect these activities to make us feel great at any cost. We have to concentrate on the activity itself, not our "feel better" goal! I've made this mistake many times. And yet, sometimes I'm doing something "just because" and all of a sudden I feel engrossed and relaxed and it's great. 
I like the way you phrased that. Yes that is EXACTLY what I mean. AND I, too, have made the mistake of engaging in an activity for the "feel better" goal. And it has failed miserably. LOL. because I was monitoring.

Getting better is NOT for the faint of heart. On the other hand, trying too hard, usually backfires. I've heard that many times here---- I'm trying so hard, I'm doing this, that and the other thing and I'm still twitching or I'm still freakin'........... oh that anxiety is a wily foe. we have to balance the "I need to do things to get better" BUT also "do it in a way that we are not allowing our mind to fixate on 'do I feel better yet' or trying so obsessively hard".
I think, often, we get those moments of clarity QUITE by accident. by that I mean, we'll be a mess anxiety-wise. we'll be so diligent with doing all the right things and almost seem like we are failing at it, 'nothing works'. Then we go and do an activity---- maybe at the urging of a friend or family and
accidently get lost in it. We have two hours (or whatever time) and feel great and are happy and enjoying the company or the hike or the movie or the football game or............ on the way home we suddenly realize you felt GOOD..... Those are teachable moments,
IF we allow them to be.
