Separate rooms 😩

So I posted yesterday about putting baby in her crib for the first time in her room and she ended up doing great! So we are sticking with it however last night I slept on the floor next to her crib and couldn’t sleep and this morning my back was killing me! My bedroom is opposite side of the house but we have a guest bedroom next to hers so I’m going to try sleeping there. My anxiety would be too bad being any further even though I have a monitor and everything I’m just afraid of not hearing something. Am I crazy and will I ever stop feeling this way and eventually be able to sleep in my room again?! Thanks for listening this far 😂
