There can be several reasons why you are feeling tired all day and experiencing symptoms of sickness. It could be due to lack of sleep, poor diet, high stress levels, or an underlying medical condition. To alleviate these feelings, it is important to prioritize getting enough quality sleep, maintaining a balanced diet with proper nutrition, managing stress through relaxation techniques or seeking professional help if needed, and consulting a healthcare provider to rule out any underlying health issues. Additionally, incorporating regular exercise into your routine can also boost energy levels and improve overall well-being. Remember to listen to your body's signals and take care of yourself both physically and mentally.
