Hard first day of school

Anyone who has been keeping up with my post, I took in one of my son's friends. He grew up extremely wealthy. His lived in a multimillion dollar home and has never had to do anything for himself. His family lost it all because both his parents committed severe tax fraud and embezzlement and are in jail for it. So since they were arrested he and his siblings have been put in foster all. All their assets have been seized. I've been really patient with him because the only life he's ever known has been taken from him. He doesn't know how to cook or clean or do laundry or anything for himself. They had their first day of school today and he's went to private school his whole life. He's spending his senior year in a public school. I guess it was a huge culture shock because at his private school students stay in the same classroom all day except when going to the bathroom or an elective. Teachers rotate through the classrooms and cooks bring lunch to them. So he got extremely overwhelmed trying to get through the hallways and had a severe panic attack. He's never had a panic attack before so that was scary for him and there were so many kids in the hallway. Do I had to pick him up and now he just wants to get his GED and not go back. I would have to ask his caseworker. But I don't think he should quit after one day. He will miss homecoming, senior prom. Senior field trip. But I understand it's all overwhelming for him. Would it be better for me to just talk to his caseworker about letting him get his GED or have him try at school again

Edit: I'm sorry if it came off I was blaming his money. I think he was just extremely sheltered. I also think he's stressed out because he hasn't seen his siblings in 3 weeks or even heard from them. His younger brother we found out is getting moved to a behavioral home. He has only been able to speak to his parents twice since they were arrested. I think the crowded school just broke him with everything else going on. I think it's more too many things are changing at one time and while his parents weren't great parents they were still his parents so not getting to talk to them has had an effect on him. I think multiple things caused this panic attack. The crowded school just pushed him over.
