Room transition

Ladies how did you handle transferring your child to their own room? My son is 1 years old (14months) and we’re transitioning him to his own room after being in our room for all his life. He’s also sleeping in a toddler bed, which he has been using for naps. I’m just emotional and so anxious about him sleeping so far away from me even if it’s just across the hall, I don’t know how to handle it and my husband is no help because he doesn’t understand my worries.
