Help 😭

Within the last year, my boyfriend has lost his grandmother to a drive by shooting while trying to protect the kids at her daycare, found out that this three year old child that he’s attached to is not his three days after celebrating the baby birthday and his great grandmother just passed last week. It’s is so tough. I don’t know what to do or what to say and I just need help comforting him with the right words. He is in a daze, he is always wanting to be left alone. I just want him back. I know it all takes time but I just need somewhere to start. Please anyone 😞
