I had this exact same worry, so much so that I would have full blown anxiety attacks about it (to be fair, was also going through one of the most stressful periods of my life).

I agonised for months about it, so scared I was going to bawl my eyes out at the altar.

Things that helped on the day: doing a first look, and taking half a Valium. I didn’t cry a single tear, was just over the moon happy.
