Among worldwide health problems, depression is a major health problem affecting more than 264 million people worldwide. There can be several social, economic, cultural factors that cause depression. The disturbed environment we live in, like the stressful neighborhood, insufficient social contacts among the family members, the desperate nature of unmarried and widowed people are some social factors that may cause depression. The minimum level of education, low income, unemployment, the stress of responsibilities in the carrier are some of the economic factors that can cause depression. Some barriers and beliefs of several cultures can also lead to depression.The number of people suffering from depression has increased with the COVID-19 global pandemic. It is a very distressing time which a lot of people feel overwhelmed by hopelessness and despair. It can interfere with the ability to think straight, drain energy, and make it difficult to get through the day. The stress of social isolation for a long time, the worry about jobs, money, health, and feelings of loss that many people around the world are experiencing at this moment can trigger depression for the first time or exacerbate symptoms if already been diagnosed.So, it’s essential to recognize and measure the depression of people with the resources we have. Today people use social media as a major communication medium to express their feelings and thoughts. Social media users are rapidly growing day by day. The current pandemic situation is affecting this increased rate of social media use. Through our project, we have planned to build an AI-based system and use social media (Twitter) texts and find the depression level of individuals. We hope that it will be beneficial to people suffering from depression and who need help at this difficult time.
