DS in his room a lot. On his phone constantly. I refused to turn off you tube restricted mode today and he threatened me aggressively and pushed me backwards into a radiator. He then got a screwdriver and removed the handle to our bedroom door (bullying behaviour) .DH is WFH pressured and needs to concentrate. I can't risk DS stomping off (had this before) in a lockdown situation. Not engaging with school work either. He was fine untl school ended
