19.  The world is competitive nowadays. People face competition in even the tiniest tasks and are expected to give their
                       best at every point in time. When people are unable to meet these expectations, they get stressed and could even go
                       into depression. We get to hear a lot of cases where people are depressed due to reasons like peer pressure, studies,
                       family issues, relationships, etc. and they eventually get into something that is bad for them as well as for others. So, to

                       it is easy to implement on people and also gives good results. This therapy includes understanding the behaviour and
                       mindset of a person in their normal life. With the help of CBT, therapists help people overcome their stress and live a
                       happy life.
