i 'worry' about whether this kind of thing can work.
consciously you have removed or shifted the thing that is worrying you. subconsciously you have done nothing at all, well, you have performed an action not unlike performing a ritual or token gesture (maybe that is enough for the subconscious to be satisfied).
do these conscious gestures resonate with the subconscious part of the mind - the subject you are worrying over is still there, consciously ignoring it but perhaps subconsciously fretting over it until the stress manifests itself in either physical or psychological problems.
i find myself worrying over things, sometimes real concerns, sometimes trivial things that are exaggerated because the larger concerns seem sated, i.e. the big worry hole needs to be filled with something even to the point of inventing a problem to fill it.
personally, i've found that being occupied with an activity you need to give full attention to will remove the problem of worrying about something. (oh, this is just being distracted isn't it - we all do it - i thought i was going to say something profound.) i think the point i'm trying to make is that if you are occupied you'll stop worrying about the trivial problems - they cease to be an issue and you realise they really weren't important. the other point i'd like to make is that i think, by nature, the human mind will find things to worry about or become annoyed about or become stressed about even when life is running perfectly smooth.
it's like we have a worry quota or a stress box that needs to keep topping itself up - if there isn't a real problem to satisfy it the brain will invent one as a substitute. the level of worry or stress or no less real just because the problem is a fabricated one.
probably stated the obvious there - which i'll apologize for.
edit:
just wanted to add that the 'worry/stress' thing i'm talking about is the kind that lingers in the back of your mind all day long, every day, all week, all month, all year - not the type of worry that you believe you'll make a fool of yourself at a particular moment in time like a public speaking event. though, i guess, they could well be the same thing.
