Wow Danielle! I'm amazed that you can remember so much detail about your nights out. Especially when there's alcohol involved!!
Good gawd, I can almost smell the beer!
I've been in the position of "babysitting" a bunch of drunk friends before and it's absolutely no fun. I'm not the type that can just go off and leave them though, and it sounds like you're not either. Man! Having a conscience sure does suck sometimes.
Just make sure you don't let them take advantage of your kindness.
I'm sorry you didn't have the greatest of weekends, but there will be
plenty more. There's nothing wrong with taking a weekend to relax either. You have to rest sometime, even at your young age!
