My troubles

Last (Do you mean yesterday or the day before?) afternoon I was on my way home. When After I got into the subway station I saw a familiar figure standing a train of another direction and prepared to make up a prescription to a pharmacy on the opposite platform. She was my former colleague and my good friend who She retired for last one year. She was on her way to fill a prescription at the pharmacy. She didn’t look very well and she told me about her current situation. Last month she had a heavy cough, and she felt afraid. So she went to the hospital to do have some checks run. Nothing was found. This month she had a little red noticed her stool was red. So Yesterday she went to hospital to have an do enteroscopy (this word does not exist. Do you mean endoscopy?) performed. The result was good positive. For the past This year she often saw a doctor for and reported uncomfortable feelings but she didn’t describe her health. Although nothing was found, she has taken many medicines. Because she felt so bad that she had to go to hospital (this part sounds confusing and doesn't connect with the above). The relationship between her and her child son is strained had some question all the time. Her son has not didn’t called her for three months and . Normally she never told about her son. So I suggested her to that she see a psychiatrist. I told her that maybe her pain isn’t in body wasn't physical but in emotional. She said that she knows if the relationship between her and her child son was become better, her body will would also be well. She didn’t accept my suggestion. After we said goodbye I worried about her. How do I help her understanding her question problem? You know, in China many people can accept the diseases of the body’s diseases and but do not don’t accept problems that are psychological in nature questions.

The corrected version:

Comments:

1. In English, instead of translating "child" (孩子), we are more specific and will use "son" or "daughter."

2. China is a proper name and should be capitalized.

3. In English, we do start off a sentence with "so" (所以) but it's not very often.
