My 12-year-old son doesn't doesn't care about anything.

My son has been driving me crazy. He gets into trouble at school several times a week - he keeps forgetting his things at home, he won't do his homework unless someone is standing next to him, and basically drilling him to do it. His teacher calls me every week, and they're threatening to expell him. Apparently, he just leaves in middle of a class to go to the restroom, but he stay there for solid 40 minutes, which happens every day, sometimes even more than once. No matter how many times I tell him, he won't study, and he doesn't mind in the slightest that he's failing most of his classes. Don't get me wrong, he's not a stupid kid, he just doesn't pay attention at school AT ALL, and then he doesn't do his homework at home. He won't brush his teeth or shower himself unless someone drags him into the bathroom. He wears the same shirt for a week straight and even sleep in it, even if I keep telling him to change it.When I try to have a talk with him, and ask him why he's doing all these things, he won't answer. He'll just look at the ground and won't say a word, and leaves when I'm done talking. I tried everything. Being kind and patient doesn't work. Yelling at him doesn't work. He doesn't care at all. When I'm mad at him, he comes back ten minutes later, cheerful as ever, as if nothing happened.I tried to motivate him. He kept begging me for years, so he could join the football club. I finally allowed him to go under one condition: he'd do his homework, and try to get better grades. He didn't try to improve his grades at all. He still didn't do any of his homework. So after several warnings, I told him that he's not allowed to play football until he starts trying to do something. It's been months, and he doesn't care, he doesn't want to do anything.I tell him I'd buy him a new phone if he started doing his chores and homework, he's excited for five minutes, saying "okay, mama, thank you so much", but he never does anything. When I threaten to take his phone, he still doesn't do anything. When I actually take his phone, he doesn't even try to work towards getting it back from me. It's not that he's trying to be bratty, I just feel like he doesn't care. At all.I asked him not to use his mobile data anymore once he gets the warning that he reached the limit, but he won't listen. I tell him every month, but he still keeps using it even though he knows I have to pay money for it. I have to wake him up 5 times every morning, he'll always go back to sleep. When I tell him to come downstairs, he says: "yeah, coming", but I actually have to call him many more times after that, and he bothers to come down after like half an hour.I have no idea what to do with him. Any help would be very much appreciated!TL;DR: My son won't do his homework, chores, brush his teeth, take a shower, etc. no matter whether I ask him nicely or if I yell at him. He just doesn't care about anything even if I try to motivate him or even when I punish him. via /r/Parenting https://ift.tt/2IGWu8Q
