I need help !!!

So me and my man got busy last night. One thing led to another I woke up this morning with huge hickey on my neck. I really need this thing gone by Tuesday because we’re going to be in Hawaii and make up will not stay on while swimming ect. I feel like I look like white trash and also my whole family is going to Hawaii Grandma parents aunts uncles ! I may be an adult but this is embarrassing for me! Make up isn’t an option!
