Have you ever tried focussing on your blinking? Difficult isn’t it! You either keep staring or blink too much. The more you focus on it, the more difficult it is to time your blinks! It’s just something we all do naturally without thinking.. Once you stop focussing on blinking, your blinking returns to normal.
It’s exactly the same with anxiety symptoms, the difference being they scare us whereas blinking doesn’t but if we learn not to focus on our symptoms by not thinking about them, then they too just return to normal.
I can hear you say, we know but it’s so hard to do!....but I’d reply it maybe difficult to train the mind to stop focussing on symptoms but it’s not impossible to do with practise!
