Dear Practo User,
It can be difficult, especially in the situation we are in at the moment. There could be various reasons for this that we would be able to tell you upon further enquiry. However, there are various things you could try doing. It is a possibility that you have over worked yourself, and what you need it a break/detox from your electronics or work.
Next Steps
You could speak with a psychologist so they can provide you with specific tips and self help techniques.
Health Tips
You could always make a schedule for your work time.
It is always a good idea, if you're working from home, to have a designated place only for work, where there is minimal distraction.
It is also important you find a way to create a "work environment" for yourself (this is again if you're working from home)
Take breaks, but consider your breaks as rewards for completing a particular task. Also add your breaks to your schedule.
Be careful to make your schedule reasonable, and realistic.
