I’m dealing with this currently due to mild ongoing sleep-dep. A couple of suggestions. For putting the anxious/panicky emotions into context, I’m going to recommend daily meditation. You might start with Understanding vipassana meditation on this site. For focusing on tasks—this is the hardest for me. The Pomodoro Technique works for me—for a while, before it stops working. But it does help me get over productivity slumps from time to time.
