Friendship Help? Please Help!?

I had this best friend Hannah and well Hannah and I got into a fight because i thought we had plans and it turns out that we didnt. This was at lunch on wednesday. I was kind of upset so i asked my friend steph if we could go to the bathroom so other people wouldn't hear about what I was going to say. So i got through the day and i went on the bus and plopped next to my other friend Caroline. Caroline has always been a trouble maker and a drama queen and i sensed something was wrong when she wasnt talking to me so i asked her whats wrong. and shes like im pissed at you because you said some mean things about me and you've been acting coldly. So I went home because I felt bad about the fight with Hannah and i came home crying so i was already worked up. I called Hannah and it turns out Caroline had completely hoodwinked her into things i didnt say and would never do. Hannah told me that Caroline had told her how she felt excluded by me and that i didnt invite her over for months at a time ( i invited her over about two weeks before and she hadn't been reciprocating so i didnt invite her over), also that i kept interrupting her and i kept sticking my nose into things, she also told Hannah that i said that Hannah made a ***** move when really had told steph that i had to go to the bathroom. Carolina had also said that i was stealing all of her friends when they can truly be my friends too.Hannah said that she was completely mad at me because of this and felt so bad for Caroline. I was the bigger person and called Caroline apologized and she said that she would think about my apology. This morning Caroline said that she couldn't be friends anymore and that we should go our seperate ways. I am now worried that Hannah will no longer be my friend. Please Help!
