Huge back story to this BUT I have this nightmare situation with my 15 year old son, where he has become addicted to a game on Xbox. He's about to go into final gcse year and I am not joking when I say addicted: in the last 6 months he has become lethargic, overeats, doesn't socialise, would happily stay on the game until the early hours, his schoolwork and reports have nosedived. It has become a huge source of conflict and sadness too for me. He seems very unhappy and says he is suicidal without it?! When I take it away - as now- he literally pines, won't leave his room and watches endless YouTube-ers playing the game. Any advice?? I've spoken to his Gp but nhs so long-winded. I've had no luck with therapists but would be keen for any recommendations (we are in west London). Please help!
