Write or Wrong, I am so sorry that it is so hard for you. 🙁 Holidays are hard when you have a kid who is OTD that is making life miserable for everyone else. Hoping that once he goes back to school you will have some relief.
So what are your options? And what are your son’s plans (if he shares those with you?)
I also feel bad for your other children especially those who share a room with him. I hope things will get better very soon.
Maybe your family could go away for a shabbos and he could go to one of his friends that shabbos. It might be good for all of you!
