Struggling with being in his own room

This sounds really dumb and I’m aware of it. We recently put my son in his own room because his naps in there were fantastic and it’s gone well. I do think he’s starting to teeth again so last night wasn’t his best night but the first few nights he was sleeping 6-7 hours at a time. When he was in our room his longest was about 4 hours because he knew we were there and would start crying.

I’m thrilled he’s doing great. But honestly I’m really struggling with it. I feel like I’m abandoning him in there and our room feels empty now without him sleeping in there with us. I literally get sad about it every night and feel so separated from him. I wouldn’t be surprised if this is basically separation anxiety on my part because honestly I did have anxiety surrounding him when he was born and I’m with him 24/7. But I’m just wondering if this gets any easier? We’re on night 4 or 5 i believe and I’m still just really sad when we start getting ready for bed and he’s not in there with us..
