Take good care of yourself. Make sure to get enough sleep at night, take a regular break and alone time, exercise, and eat proper nutrition. No matter how dedicated you are to your job or to your beloved, you need to keep your emotional well-being, too. Ask someone to relieve you while you take your alone time. Your disposition can affect the person in your care. When you are not in a good mood while attending to your beloved, he will pick up on it. Thus, making him more confused and agitated.
