make ur both parents and dada..make them sit somewhere..then sit in front of there leg in ground..touch them..and say all the stupid things u did..just like u shared here..
convince them u did a crime of life..and it will be ur last mistake ..make ur ma papa and brother emotional..(think of 3idiots story of that guy convincing his parents for photography)..beg them for help..ask ur ma to forget all what u have done..and be a nice and good guy..and just say them to help u rightnow..and say..dont trust me..just support me..u urself will earn there trust..seek there help..make them remember ur school life or kid life..where everyone use to live happily..and then start a new journey in life by helping them everywhere and share each and everything with them from now onwards..in every salary..buy ur ma some food or things which she like..do as much as u can like a son and like a younger brother..do gain there trust..and continue with it..i hope i can make u understand what i mean to say
