Refocusing Skills: Notice that you’re distracted and refocus back to the present moments. Most of the traditional mindful breathing mindfulness exercises will help developing this refocusing skills. You can try the Benson’s method here.
Observing Worries: If you happen to be in a private setting, try observing your thoughts. You can try leaves on the stream or the mind-train, being the observer of your experience and thought, realise that you have choice and control to not react. It requires some practice, and usually only possible to do it in private, not like when you’re in a social situation)
Rapid Unhooking Skills (noticing, naming, refocusing) notice and name them “that’s my mind worrying” “that’s I’m not good enough story” “that’s something bad will happen story”, then refocus back to what you are doing.
Acceptance of Physical Sensations: Quite often we are pulled to focus on thinking, worrying, being in our head, in order to run away from unwanted feelings and sensations in the body. Notice that you’re pulled into your head, then check feelings/sensations (e.g. sweaty palm, heavy chest, upset stomach, racing heart, numb fingers) in your body then try to allow those sensations.
Use it as a trigger to reconnect with your values: if you’re worrying about your health, then obviously your health is important to you, decide how you want to treat your body, decide the behaviour to improve that, take actions, rather than just thinking about it over and over again.
Reminder to practice Self-Compassions: life is difficult, a lot of challenges, obstacles and loss, acknowledge that it’s not easy and be there for myself, soothing yourself.
Cue to start Problem Solving: Worry = fruitless problem solving. If it’s an important topic and a solvable matter, how about finding a time to sit down and properly solve it?
