My friend

So me and my friends went out for the night the other day (it was one of their birthdays) so we went to a restaurant and I sat down had a good chat with everyone and then the topic of boobs came up and how they grow etc, etc, and keep in mind I have small boobs and I don’t really feel good when people comment on it so anyways I said oh yeah my boobs had gotten a bit bigger because of my period and my friend that was sitting beside me made a face and looked at the others then tapped/poked at my boob laughing so that made me kinda mad but I was kinda used to that so I let it slide I guess.. later on that night that same friend got really drunk and I had to take care of her for the most part and she threw up a lot and kept saying sorry I had tried to get her to drink water but she threw it at me saying she’d get ecoli.. so by then I was getting pretty mad and sick of it and she kept spitting everywhere every few seconds and complaining about wanting to go home and how she couldn’t find her phone so then I decided to leave her with my other friend for a bit while I got away for a bit because honestly.. I know it sounds bad but I was mad. So then I came back and me and my other friend had to ask these older guys in college to give us a lift home and on the way she kept putting the window down and spitting out of it and when we got to my house she kept complaining and begging me not to tell my mom about her throwing up etc. So I said it’s fine leave it I won’t etc. And when we got to my room I started getting ready for bed and she suddenly comes into my bathroom when I was brushing my teeth and throws up in my sink so at that point I was very mad but contained it and told her to clean it up and she kept apologising constantly to the point where it was annoying and a bit pathetic so I made her clean it up and I went to bed so did she and she went home the next morning. And because of recent events she somehow wasn’t able to study or do her homework so she texts and asks me to give her my notes and answers because she needs to study for a test tomorrow even tho the work was yesterday’s and I had done it despite having 5 tests to study for within the next 2 days and her excuse is having an Irish test to study for and that’s why she won’t do it and wants mine. I really don’t want to give it to her and I don’t think I will I’ve just had enough and I’ve been brewing over my anger with this whole thing for a few days now. This is the short version of the story of why I’m very pissed at my friend
