People that offer to help you really want to so don’t hesitate to let them it makes him feel less helpless in this situation and able to show all their love for Jon ,Rafa and you. Does RAFA have someone like a counselor to talk to outside of the family sometimes it’s good to get someone who’s a little distance from the close family , someone who makes him feel he can be honest about his feelings .and not try to say what he thinks he should. I’m not trying to tell you what to do, but it’s just an idea. I worked with a lot of kids in the psych hospital regarding grieve and loss. Keep those angels near.xo
