Screwed up again

Last week I RSVPd to my friend's wedding for next May to say I'd be there.

Last night we booked a holiday and at the last minute changed the airport we were flying from.

I did not think to check if this changed the dates of the flight.

It did.

Now flying back on the day of her wedding.

It's going to cost nearly half the cost of the holiday to change the dates.

I feel sick. I absolutely hate myself.

The worst part is how ADHD is just perceived as carelessness. I don't WANT to be like this!! I absolutely hate myself for this! I try SO HARD to check and double check everything. I try to have planners and calendars and reminders. But it doesn't always work. I don't want to be the asshole that booked a holiday on the day of my friend's wedding. I really, really wish I wasn't like this.
