I've namechanged
My grandson is 18 and he lives with us as his mum was a drug addict and he was neglected. My son had full custody of him when he was 1 but he passed away due to suicide. He was depressed but he just told everyone he was ok. I'm worried about grandson as he doesn't seem himself, he's quiet and doesn't eat much and he's always in his room. Yesterday he didn't eat anything I don't think as he kept saying he wasn't hungry. Today he agreed to come with me to walk the dog (he doesn't go out either normally) and he told me nothings wrong and that he's just bored. I don't believe him and I told husband I'm worried about him but he told me to leave him alone and that I'm overreacting.
Aibu? Would you be worried
