FOCUS, I really struggled with this one myself; I was always doing 20 things at once! Being a person who always has lots on the go can sometimes be about genetics and temperament. However a lack of focus is also a common side effect from the heightened arousal that comes with fear, anxiety and panic. It is hard to focus when your mind and body are being bombarded by anxious thought, feelings and sensations! The use of avoidance strategies can also result in us being scattered and unfocused.
For example, if you are using being busy, or distraction to help avoid your Fear, Anxiety or Panic, then this makes it almost impossible to have the inner calm and focus needed to fully be with something. Do you find that you are often starting things, but not getting finished? Switching from task to task, and getting to the end of your day, and feeling that nothing has really been accomplished?
A common thing that happens when you use this type of avoidance strategy is that when you get to the end of the day and go to bed, you can get flooded with all the things you had been avoiding throughout the day and cannot fall asleep. Learning how to focus more fully might be just what you focus on!
I have no magic bullet here, although for me two things really helped to improve my focus (EEG biofeedback and Mindfulness Meditation). Basically I just had to practice. Every time I lost focus and became scattered or distracted I had to practice bringing my attention back and refocusing on what I was doing.
Both EEG Biofeedback and Mindfulness Meditation really supported me to develop this skill and I have written about these already, see the links below for more information on these two techniques.
