Hi dear
Excessive work and pressure from surroundings tend to get along stress and disturbance in mental peace.
Try and include exercises or some physical activity in your routine for de-stress. Avoid excessive screen time, spend time with your friends or family, take breaks within work, decluster your work station/your room/ your house.
Make achievable goals at work.
