& your dad nor should anyone force contact. I would have the vet check him out just in case.
That said for cats that frighten easily safe bolt holes make them feel better. So you can easily try putting a box on it’s side and draping a towel draped over half or 2/3’s of the entrance. I would give him a safe place to hide in the living room (at least for a couple of months.) I would also get your dad & all guests to agree (before coming over) that if the cat is in your/his room or one of his hiding boxes, the cat is not to be touched at all. I did tell my niece though that she could lure the cats out with a wand toy. However if the cats wants down, moved away, tail starts flicking then all touching needs to stop. Like I tell her, be the furniture. My guy feels safest up high, so I got him a 7 foot tall cat tree. You can also get your cat cat shelves. Some cats feel safest down low. So I left the cat cube with his sister, who is a bush dweller (you could always drape a baby blanket or lap blanket or towel over the cat cube entrance.
