Is the dr's office opened today that prescribed them? If so, call them and have them call in four to another pharmacy that's open? Even if it's not open, I would call the emergency number and have someone paged. That's what they are there for too.
I know it's hard not to beat yourself up for forgetting something of this magnitude. I do it all the time.

Do you have a calendar on your computer? Can you pet med refills in on that? I've been doing alot more of that.
Please let us know hon.

PS, I'm proud of you for a private thing too.
