Depression is more and more popular and serious in young people therefore this research paper is carried out to provide information about symptoms, causes, effects, and treatments of depression in the young. 2-Discussion of findings  2.1. Symptoms Like other diseases, depression also has its own manifestations. According to Headspace-National Youth Mental Health Foundation (2007), Mayo Clinic (2017) and Better Health Channel (2017) there are eight symptoms of depression on young people. The first sign is feeling sad, helpless and hopeless. Everything that happens around you becomes meaningless, you are not interested in anything. The second is angry and irritability, means that everything even over small problem also make depressed people angry, feels uncomfortable. Feeling of worthlessness or culpability is the third sign of depression, people under depression always feel guilt and blame themselves. The next symptom is the shortage of energy, vitality and motivation, which make depressed people looks dull, does not have strength to do anything. In addition, you will have problem with sleeping when you are depressed, it means you can sleep less or more than usual even as almost all day. No less important is eating disorder. If eating well, the weight will increase significantly; if not eating well, the weight also decrease quite a lot. Besides, there are the trouble making decisions and ability to concentrate. Last but not least, depressive people often think about death or suicide because of feeling of helplessness, hopelessness, worthlessness and guilt. In general, symptoms of depression are varied and difficult to recognize at the beginning of illness. However, the late detection of a depressed person will lead to adverse effects and difficulties in the treatment. 2.2. CausesKnown as a popular illness, depression may be caused by hereditary factors or biological ones, dope or smoking. However, at different age depression is caused by different factors. According to Action Mental Health (AMH) and Better Health Chanel (2017), there are two main causes of depression in young people they are pressure from studying and working and problem in relationships2.2.1-Pressure from studying and workingReferring to school, people often think about healthy environment, an ideal place for studying, making friends. Contrast with wonderful appearance, students have to face with a lot of pressures. They experience the stress examination, there are more and more test in one school year, and with many homework. As a result, students do not have time to relax, lead to be tired, listless. In addition, if they get low mark, do wrong tasks, they can receive criticisms from teacher or parents, which make them feel useless, depressing. Nevertheless, children’ studying is often expected by parents, who want to their children become a perfect person or study follow their way, continue their work. Parents do not find what children like, what children want to do, what children want to become, instead of that they usually pre-direction and then take children to follow. Expectations of parents too much make children feel uncomfortable and have no interest in doing. After graduation and have a work, think that there are less pressure than studying; however, the working environment is not the same as the learning environment, therefore pressures are not the same. When working, you must be under pressure from manager, boss, colleagues, with the large number of deadlines every week, sale imposition and do not have much time for rest. The similar with studying, if you do not well you will be told off, your coworker will be disdainful and have bad words about your ability. Time also is problem with people in work. In that moment, you also feel tired, worthless and depressed at work. In fact that, as society grows, the needs for life are increasing, which take people on the race to try to perfect in the way society looks. Humans attach importance to the remarks of others, often more criticisms than compliments; absorbing negative things people will lose confidence, the self-trust, leading to depression and suicide. For instance, in December, 2017, the young famous singer of Korea Kim Jonghyun committed suicide at home, which was a huge shock of his family, friends, fans; the cause of this heartache is Jonghyun’s depression, which was caused by pressure from his singing career. It is also common of knowledge that there are many celebrities in the world who committed suicide because of depression such as: Chris Cornell (the leader of Soundgarden band), actor Park Yong Ha (actor of the film Winter Sonata).  2.2.2-Stressful relationshipsThe first is relationship in family.
