I recommend going to sleep if possible, or persevering with sleep in mind as something to look forward to. After waking, one tends to have a more harmonious frame of mind.<p>A sense of depression (and I assume you&#x27;re referring to the emotion, not the medical condition) quite often has nothing to do with easily identified circumstances, the mind just tends toward the things it is dissatisfied with.<p>If you believe you have the medical condition, treat it like anything else: see a doctor. I know many people who have wasted years of their lives fearing a few moments of awkward discussion with their general practitioner. There&#x27;s no rational reason to join them.
