I thought it was finally getting better, but obviously it's not!! Girl, it sounds like you have a roommate and friend (if that's what you want to call her) from HELL. I know how important girlfriends are, but at this point I would tell that girl that she is NOT allowed in your house. You should not have to resort to medication because of inconsiderate jerks that you are living with. Your 'real' roommate is being a huge jerk, and not respecting you in the least. You both pay to live there and you BOTH make the rules. If he can't adhere to the biggest roommate rule of all (RESPECT) then it's time you tell him where to put it. I know yelling isn't going to fix anything and that's not what I'm suggesting. Maybe you should tell him and the girl that you don't want her over there anymore. Or make a rule that no one is allow over after 12am. It's a shame that neither of them are willing to compromise with you, and it's even more of a shame that this girl just keeps lying to you to keep you quiet. Why would she keep saying sorry, and then repeat her actions over and over again? I'm so sorry you are having to go through this. It's not fair on you at all. Even if you lose this girl as a friend, it sounds like your health is much more worth HER friendship. Good luck.

I went to school this morning fully ready to explain my situation, that even when they fall asleep i'm so stressed out I'm up all night. I started out by asking the girl if she would mind if they slept at her house tonight and she BURST OUT LAUGHING! She said yeah, but just the fact that she laughed at me made me so mad I just quit talking to her. The other girl in my class, who is now like the only real friend I have here, was so sympathetic when she saw me this morning. She said "oh you look so tired!" and I told her I slept 3 hours last night. The first girl was like "'I'm sorry! I really am!"with a huge smile on her face.
She wants everyone to know so badly. If I threaten to tell, she'd definitely come over more. My roommate is the only one who really really doesn't want it to get out, and I'm not near comfortable enough to discuss anything with him. Her and I having a fight right now would make for a very awkward three months when we have to sit together every day, all day. She's also good friends with my boyfriend. She grew up with his roommate and their whole group of friends, so if something happened I would feel excluded from the group.
I really don't know what else I can do but suck it up for 3 more months.

Okay! I think I have gotten through. I'm talking to her on MSN right now. She asked if it was them or my dog that kept me up last night, and I said both for the start, then it was quiet but I get so stressed out I can't sleep for the rest of the night. I apologized for sounding bitchy, but I told her if she wants to come over and hang out with him and whatever, if they're quiet by midnight it's fine with me. Her exact words were: "No that is ok, I want to you tell me if we are disturbing you, i really don't mean to" and then "no seriously lindsey you are my best girlfriend here and the last thing i want to do is piss you off" She's at home right now but my roommate is out with some friends. She told me "at least you'll get a good sleep tonight" and I said it depends on how late my roommate gets back, and she was like "No, I think he's coming over here when he's done."
I'm praying that this will go on for more than one day!

Girl, you've got to make a change for your health. Careful with the Tylenol. It's safe in proper doses, easy on the stomach, but is actually a very dangerous drug and can be very toxic if you take too much. It can cause liver damage and there is no antidote for an overdose.

GOOD!!! I hope so girl. Get that sleep tonight!!
