Loneliness is an issue of heart feeling without any, depression is a psychological problem that the world is in its end, heartbreaks are purely setbacks which time will cure. We have to firstly want to admit and acknowledge ourselves that we are who we are and changing our perspective would help us definitely. Finding help is not weakness yet strength, the depressed,lonely and heartbroken must see the sunshine in the mist of the dark time and seek help from friends, family and teachers.
Putting up a front is just to hide yourself not from your friends but yourself. It is oneself who is afraid of yourself. We can show our real characters to our closest friends and tell them of these and ask them to be understanding.
