How to get rid of hickeys and excuses for it?

I have senior pictures in 3 days and work in 2 and there’s no way to hide it. I know makeup is one of them but I feel like they’re so dark that it won’t help and you can still feel it. I need excuses for my parents as well if they happened to see it which I’m praying they won’t. Any excuses and ways to get rid of hickeys asap??
