Please help with these canker sores!

As I mentioned in my last, much more loaded question, this past week has been Hell week at my university. My stress levels have been so bad because of it and I think they have started some sort of epidemic in my mouth. I got two canker sores on Friday, a new one Saturday, and new one Sunday, and a new one today. Please help!! It’s really horrible and they keep coming…...I can barely eat at this point and brushing my teeth is an absolute nightmare :(

Any quick remedies?
