Jack is a psychiatrist, which means he treats people who have mental problems.
He has been treating patients for many years and has used a variety of treatments.
Sometimes he just listens and talks to patients, and sometimes he uses medications.
These medications affect the brain in many different ways.
（He has been a psychiatrist for many years.）
（As a psychiatrist he treats people who have mental problems.）
Over the years, Jack found that some patients improved with treatment while others didn't improve at all.
In some cases, a patient's response to a treatment was the opposite of what was expected.
Several years ago, he had a young patient who showed him why these treatments didn't work.
The patient's name was Bob.
He was 20 years old when he first came to see Jack for help.
The reason he came was that he had attempted suicide.
（If he hadn't attempted suicide he wouldn't have come to see Jack.）
（He wouldn't have come to see Jack if he hadn't tried to kill himself.）
Bob was extremely smart and was a student at one of the best universities in the world.
However, he was often extremely depressed.
Because of his depression, he took drugs and drank a lot of alcohol.
It was an overdose of drugs and alcohol that nearly killed him.
His roommate called 911 when he discovered Bob unconscious in their dormitory room.
（If his roommate hadn't called 911，Bob would probably have died.）
（He took drugs and drank a lot of because of his depression.）
Once Bob recovered and was discharged from the hospital, he took time off from school to get help.
That was when he came to the clinic where Jack practices medicine.
At first, Jack attempted to treat Bob with antidepressant medications.
He also used conversation and recommendations to help him rethink his life and memories.
After a few months, Bob began to improve, but only moderately.
Though he cooperated with the treatment, he continued to think negatively.
He also continued to go through periods of depression.
As a result, he wasn't able to return to school.
（had the treatment been successful，he probably would have returned to school .）
（He wasn't able to return to school because his treatment wasn't working.）
（He was still going through periods of depression.）
