Meditation for Work Anxiety I started a new job, and when I get anxious my cognition turns to pure incoherence. I second-guess everything, doubt, double-check unnecessarily, make more errors, etc. 

What is the best type of meditation to deal with such anxiety-related problems?
If the anxiety is light yet bothersome, gentle restrain anxiety by relinquishing attachment to outcome:


  This is not mine, I am not this, this is not my self. MN62


If the anxiety is heavier and a bit overwhelming, a firm restraint can be achieved by slowing the breath--rapid breathing promotes anxiety. Regular practice of mindfulness of breathing helps.


  When mindfulness of breathing is developed and cultivated it’s very fruitful and beneficial. MN62


Generally, the more you practice the Noble Eight-Fold Path, the more equanimity emerges with the fading away of attachments to identity view. However, that practice and its fruition are gradual. For the longer term, precepts can be enormously helpful.


  A mendicant might wish: ‘May I prevail over fear and dread, and may fear and dread not prevail over me. May I live having mastered fear and dread whenever they arise.’ So let them fulfill their precepts … AN10.71


Also consult with your doctor for additional recommendations. Some anxiety disorders can be quite crippling and medical assistance can be of great benefit.
