Hi barun, everybody will not living happily as they are express outside so there may be some difficulties u have faced in ur life till now and it does not mean it will going to continue in future. Having responsibilities in this age makes u be mature then others. The thing is u are not sharing about ur good and bad with any all the things making u to struggle inside only, so try to make frds or have someone who can listen to ur problems then only u can feel better. Don’t think u hav wasted ur life , it will definitely give u a good result. So be positive with all the things happens in ur life and be confidence on urself and face everything comes in ur way then u will definitely have success in ur life..
