First night away from baby

I have to leave town for a work conference. I’m having a lot of separation anxiety over it. Baby girl is 5 months old, breastfed, and has never had a night without me. She still wakes for feedings and gets fussy at times throughout the night. My husband sleeps like a rock, an absolute rock. I tend to her 95% of the time while he just lays there snoring and gets angry if I do wake him, then doesn’t remember it ever happening. He’s a great dad and I trust him 100% during the day, but this overnight has me nervous. Just looking to hear from anyone whose been in a similar situation. I need reassurance, encouragement, or advice to help get me through! 😭
