What a Friend...

So, I'm in college and my roommate is my best friend.  Well recently things have been really tough on me and I've been sick.  I thought I was catching the flu earlier in the week and my roommate was a total bitch to me about it.  Tuesday I woke up and couldn't get out of bed because my head felt like it was going to explode and I was running a fever of 101.  When I asked for a blanket she asked me if I was aware that I only had a cold...  Later at lunch she compared me to her best guy friend when he's sick.  She was saying how I was just like him and he's such a baby and whiny when he's sick.  This really pissed me off because I was feeling like shit.  I went to talk to one of our mutual friends about it and she told me to stop complaining.  Later she brought me something to drink and spent the afternoon watching TV with me.   Our little "group" of about 8 friends ended up hearing that I was mad at my roommate for being a bitch and so they all turned on me for "gossipping" about my roommate... I got bitched at for talking about my roommate behind her back when they were ALL sitting in the hallway of our dorm talking about me while I was sick in bed!   My roommate never asked how I was doing or if I needed anything... But when our neighbor was feeling a little queasy one day, she wouldn't leave her side..  She's supposed to be my best friend, they ALL are, yet I feel like they are all ganging up on me.  They get mad at me for talking behind their backs, but then they do the exact same thing.  I can't talk to any of them because they just go tell each other... I'm not sure what to do at this point.
