Supporting my boyfriend through a difficult time

my bf has family in the hospital being taken off life support today... he's not processing and asked to go alone to the hospital... which I understand... I personally use getting chores done to distract me. as a coping mechanism when I'm not processing... but ive finished chores at the house and can't really get anything else done without my car, which he borrowed to go to the hospital... I don't know how long he's going to be either.... so I don't have a way to process and feel like I'm going stir crazy without the ability to go get things done. I also want to be here for him if he needs any support himself, but im just.... idk what to do with myself while I wait, especially considering idk how long I'm going to be waiting
