Dog doesn’t want to be with me anymore

My 3 dogs are generally very attached to me and follow me wherever I go in the house. When I’m in my room, they’re also usually in there. Two of my dogs usually sleep in the bedroom with me

Recently one of my dogs has had a ivdd flare up and has been staying in my room for most of the day when I’m not taking her out to go potty. This past week or so, I’ve noticed that the two other dogs have been more distant. They don’t follow me around as much and one of the dogs who would sleep with me at night has been sleeping in the hallway.

Ive tried to coax him into my room with treats but it seems like he’s kinda avoiding it/refusing to go in. He can and has but just doesn’t seem like he wants to. And this was the same dog that has separation anxiety and would cry if I didn’t let him in in the past. I spend a good portion of my day in my room and he’s just hanging out in the hallway, sometimes right in front of my door.

I’m not sure if it’s related to my other dogs flare up as my one of my siblings did also come home from college around this time so that might also have something to do with it. That sibling has been going in and out of the house which might be making him anxious, possibly.

Idk, I’m just so sad that he’s been acting this way. Maybe he’s also feeding off my nervous energy with caring for my other dog, and other issues I’ve been dealing with.
