Anxiety before an exam, a presentation, or an important work deadline

You might notice

• Insomnia the night, or nights, before the date, with your mind automatically running through failure scenarios.
• A sudden mental blank the moment performance actually begins, even though you knew the material well minutes earlier.
• Excessive review well past the point of usefulness — rereading the same material dozens of times with no real added value, purely to quiet the anxiety.
• Physical symptoms just before the moment: cold or shaking hands, an unsettled stomach, a voice that trembles as you begin speaking.
• A strong urge to postpone preparing altogether, to escape facing the anxiety, followed by a frantic last-minute scramble.

What generally helps

• Five minutes before the exam or presentation, run three rounds of 4-7-8 breathing, then write down the realistic worst case and exactly how you would actually handle it — putting the plan on paper redirects the anxious energy from "what if" into a concrete action.
• In the final days, replace passive review (rereading) with active recall (testing yourself from memory without looking at your notes) — it locks in the material more deeply and lowers the odds of a mental blank in the moment.
• Actually rehearse the first thirty seconds of the presentation, or the first expected answer, out loud — not just in your head. The real start is the hardest moment, and rehearsing it physically takes the edge off when it actually arrives.
• Remind yourself that some tension sharpens performance rather than ruining it — the goal is not zero anxiety, but bringing its intensity down to a level that focuses you instead of freezing you.
• The night before, set a firm cutoff for studying (say, nothing after ten) and follow a routine that calms your body instead of one more anxious review pass — enough sleep helps your performance more than one extra hour of worried cramming.
