A person experienced a burnout around 2 years ago that began with heightened focus and stress at work while suppressing negative emotions and physical symptoms. Over time, their memory got worse and they became sick if taking more than 2 days off. It took over a year to recover, going through stages of acceptance, understanding the causes, and slowly implementing new work habits to prevent recurrence like limiting hours and taking regular breaks. Key lessons were that our bodies need rest to heal, it's important to say no and avoid constant stress, and we must experience our emotions to process situations rather than suppressing them.
