I am a 23-year-old male working in a high-pressure corporate job. For the past year, I've been working 10–12 hours a day. Recently, I've been experiencing significant mental fatigue, work-related stress, and burnout. Over the last 2–3 days, I've barely been able to sleep despite feeling exhausted. My mind keeps thinking about work, and I feel mentally drained and anxious. I would like to know if this is stress-related insomnia and what treatment or consultation would be appropriate.
