Sometimes using a drug to feel better temporarily can help us to have the ability to focus on solving problems, but sometimes using a drug to feel better in the short run can take away our motivation to solve some problem that will make us feel better in the long run. It does not logically follow that ingesting drugs is necessary to rebalance the brain's chemistry. An argument that is frequently used in favor of drug therapy for emotional problems is that people often suffer from chemical imbalances in their brains, and drugs are needed to rebalance them. It is true that all normal people sometimes suffer from imbalances in their brain chemicals. Brain chemicals are constantly fluctuating as the person interacts with life.
People can take drugs to rebalance brain chemicals.
However, it does not logically follow that ingesting drugs is necessary to rebalance the brain's chemistry. There are a number of other ways a person can change the balance of brain chemicals. It is recognized that things such as psychotherapy and even physical exercise can affect brain chemistry. Everyone has also had the experience of feeling down in the dumps and feeling better after talking with an empathic friend. Gaining a new perspective on a particular problem or situation has the power to change brain chemicals.
