I have learned a lot about clinical psychology last year. Psychology examines the behavioral and mental events people have been doing since the primitive ages. When psychology comes into the medical world, it usually deals with mental problems. The reason why I started to get interested in psychology was that I had mental problems last years. In the past few years, I had been in a long-term depression because of what I had lived in my personal life. Later, this depression was followed by anxiety disorder and then panic disorder. My interest in clinical psychology started when I went to the hospital to be treated. In clinical psychology, experts are divided into two. Psychologists and psychiatrist. In Turkey, the doctors who are called as psychiatrist, study and learn much more about psychology than psychologists. Psychologists usually choose the talking way to cure their patients, and when he/she is inadequate, he/she directs them to the psychiatrist. Psychiatrist, more scientifically, chooses medication. Drugs vary according to the level of the disease and also vary according to the individual. Two patients with the same disease may be treated by different drugs. Drugs for depression and other mental disorders are usually used to regulate the hormone serotonin in the brain, or they alter the balance of other certain chemicals. Although these drugs are used to cure person, they may also lead to much more bad situations. Like, increased appetite and weight gain, increased anxiety, fatigue and drowsiness, insomnia or even commiting suicide. This is why, these drugs should not be used without doctor's advice. Also, in the treatment process, you should always be in touch with your doctor and if you feel something is worse, you should see your doctor and tell the any side effect you feel.
