Mr.Black's problems

My name is David Black.I live in a small house.When I eat and drink,I am always worried they are dirty.So when I am hungry or thirsty,I don't want to eat food or drink water.And I never go out when the weather is cold or hot,because I am worried I'll have a cold.I don't go out often because I don't want to talk with others.I hardly exercise,but sometimes I take a walk in my garden.After I walk for a few minutes,I have to take a rest.I am always very weak and tired.I often have a headache,but I don't want to see a doctor.What should I do?

Dr.Smith's advice

Traditional Chinese doctors believe we need a balance of yin and yang to be healthy.I think you have too much yin because you are always worried about something and you don't like going out or talking with others.I think you should eat some yang foods,like beef and you need to exercise more.Also,talking with others can make you feel relaxed.And if you don't feel very well,it's important for you to go to see a doctor.And you will feel better after you take some Chinese medicine.
