leaving a show due to medical issue? - refund or anything?

currently at paranormal activity. i do have anxiety but i haven't had a panic attack in years. not even 5 minutes into the show i had to leave because i started having a panic attack. has anyone had experience with something like this? if i reach out to mirvish to get a refund or a comp ticket to a different show would they do it? id hate to lose all the money i spent on this ticket
