I hate making decisions. I am the worst.

Here is my problem. My friend has been planing to go to the dominican for a little while and wants me to go. I can afford it. My concern is this: she most likely will want to drink A LOT. Also, she likes to "chase" guys...if you know what I mean. Complete strangers. This isn't me. I don't like to be wasted, and I don't want to do stupid things with strange guys. She said she doesn't plan to do this all the time, and said she wants to do all the fun stuff too.

So what do I do? I can't decide if I should go. Half of me says GO! The other half says NO WAY! How do I know??
