I agree with Primis, you should call them all and just apologize for what happened and explain it was a mistake and nothing will be happening. But also make sure from your friend that she was telling the truth because she could have been lying and you have made another fool of yourself.
You don't want nasty rumors going around since you do usually keep to yourself. I wouldn't want that for you.
This can happen the first time you drink thats why you should never drink that much if you do decide to drink. I hope you learned something from this and I am glad you have decided to wait to drink. Prefrably until you are 21 and can make responsible decisons when it comes to alcohol.
