Hello everyone my name is robin let me tell u my story which is literally like others out there i've been depressed since my parents divorced each other when i was just 11 years old . they usually have fights which completely ruined my childhood i never got any love affection from both of my parents i was living with my mom she used to work hard so that i could get better life but indeed she suddenly fell so sick , she use to ignore her medical attentions just to save money but as the day went her health started to get even worse i used to take care of her but one day when i came from school what i saw just.blew my mind away there was drop of blood everywhere i follow it through bedroom where my mother was lying dead with a knife .....did she just stabbed herself? no. this couldn't be happening i was shocked my body freezes i couldn't move anymore ..then i saw a piece of paper with blood stain something was written in it . my dear son, sorry for not being a good mom i really loved u but i didn't wanted to be a burden to u so i just can't stand it anymore . and in the drawer there's a money that i've saved for u though it's not enough but u can survive with it for 3 months u wont be alone anymore ive talked to your uncle he'll take care of u my dear son love u ..... i wasn't able to utter any word why u did this mom just why. then i called police cause i was not sure whether its a murder or suicide cause i suspect my father, police arrived investigation started my neighbours came to comfort me even my uncle came he said that he would take me with him , it was really a dark day for me.
