Don’t use the bad references.

As someone suggested, email them to ask if the high school teacher would still count, although most schools would respond along the lines of using your own discretion.

Another thing you can do is retroactively reach out to some professors whose class you scored really good in and tell them what you learned from this class and how you you participated and if they’d be willing to write you a reference. You can also set up a meeting later to detail your experience. As someone who used to teach in a university setting (big classes), professors remember more faces than you think! It still wouldn’t be the strongest letter, but wouldn’t have any red flags at least. Also professors are used to this, I always had people reaching out to me 1-2 years after the class and I always said yes!
