12yo boy struggling

My son recently told us that he's drawn toward spending so much time on YT or games because he feels he needs to distract his mind from being preoccupied with negative thoughts (death, bad thi nbn gs happening the world, etc) This was part of his response to a discussion of missing assignments and subsequent consequences of losing screen time.This is a bright kid. He's previously had therapy for loss of several grandparents. He struggles with organizational skills. He also has been lying about turning stuff in, although that isn't new.He refused therapy again. A part of me thinks he's creatively trying a bit of a dramatization so we're empathetic instead of disappointed about the missing work.Anyone have effective strategies for helping him stay on top of stuff and/or ways for him to focus on thinking positively? He's scoffed at my suggestions but it's probably because they were my ideas and not his. He doesn't have any ideas and takes a nihilist perspective. Sigh... via /r/Parenting https://ift.tt/2Pd65Xw
