Lonely At 16

When I was 16 my dad died and that was the day my life ended. I have never gotten over his death and to me its like bad dream that I cant wake up from. I Had to go live with my dad after I was taken away from my mother at 13 and we bcame even closer. Im very much like my dad, the food I eat, the way I talk. I sometimes find myself saying, well Ill see him soon, like im waiting for him to come back home, as if he is on vacation!!! Ive been lonely and agry ever since and I just dont know what to do!!!
