Please give me example on how do anti depression medicine help me if i take 1 time only before an event i have. plz help? please

Using antidepressant: Anti-depressant medication doesn't work, unfortunately, after just taking one time. They take effect after taking them consistently, and it usually takes 4-6 weeks to notice robust effects from them. Using other techniques, like deep breathing, guided imagery, meditation, or physical exercise could be tried to help you with more immediate effects.
