My mother has one chronic disease, and feels very bad, even though taking medicines everyday. If she does not wait to see me, she will stop taking medicines.
Now I do not know when I should go back to China, because once I go back and see her, she will not take medicine and pass away very soon. However, If I go back late, I am afraid I can not see my mother again.
It is very very hard to decide when I should go back.
