The reason for the burnout we experience is our desire for validation from others. When you tend to expect appreciation from others, that's where the internal struggle grows and your productivity declines. 

It leads to physical and emotional exhaustion. Try to prioritize yourself and remove the source of stress from your life. When you take care of yourself, you're in a healthy environment and your productivity will flourish. You can also take a step back to resolve this problem. Give yourself a work free, stress free weekend away from gadgets. 
Have a good week.
