TIFU by mixing up the concert date of my favorite artist

At the end of February I bought tickets to go see Orla Gartland. She is based in the UK and I got super attached to her “woman on the internet” album over Covid and beyond. When she had initially announced she was going to tour in the US, I was ecstatic.
Then when I checked the Chicago venue, it was 21+ (which I am not). I preordered her album instead and hoped for another tour.
Well that’s when I received the email in February containing information about another tour in the US! but the only venues even close to me were in OH, when I live in IL. Now it’s not the worst drive ever (5 1/2 hours from where I am), but I nothing I would’ve done on my own. Thankfully, I have a wonderful and compassionate boyfriend who was willing to drive with me out there and go with me to the concert.
I bought the tickets and have looked forward ever since. Well. I guess I had somehow misread my planner and marked the date as Tuesday, April 29th. Well the concert is actually today, Sunday, April 27th. I was booking our air bnb for the night and confirming all the info when I realized how much I really screwed myself.
My heart is just shattered, because I work tomorrow and my boyfriend is out with a friend tonight (it’s 4:30AM as I write this. I have insomnia so I typically can’t sleep, and this hasn’t helped very much…), so I don’t even know when he’ll wake up and read my texts so there absolutely no logical way of making it to this concert.
I feel so stupid and shameful. I don’t know if I’ll ever realistically have the opportunity to see her again. And I won’t be able to get a refund obviously, so that’s a $75 down the drain punch in the gut. But I guess I save money on the air bnb and gas it would’ve taken and I work my shift so there’s that positive.
That’s the only thing I have to keep me sane right now since my boyfriends away. (We live together<3) I probably won’t even get to sleep tonight and I have work at 1. What a joke.

TL;DR I misread the date for concert tickets to see Orla Gartland as a Tuesday instead of a Sunday, but when confirming the air bnb location, I noticed the date was for Sunday(today). There’s no possible way for me to make it to the concert anymore. Life sucks. I’m out of $75.
