'Kay, so this is kind of a long story. I just started High School in a different city (I live in a small town and my parents want me to have a good education...I commute for 1-2hours every day...there and back...It's complicated

) and only one of my friends came with me. At the beginning of the year, I met a group of girls that I thought were pretty nice. Then, about a month and a half ago, a couple of the girls decided to suddenly change their minds. The unofficial "leader" of the group, Mikayla, and her "puppet", Shauna, cornered me after our school retreat and told me that I was following them around too much and that I should "give them some space". Basically, they told me to get lost. The little group that I was part of has 6 girls in it. Two of them are really nice, but Mikayla has made it so that I can't go near them. I ignored them at first, but a couple weeks ago, they cornered me again and said the same thing, in front of some of the seniors who happen to be related to them. So now, I'm scared not to listen to Mikayla and Shauna. I can't see my friends, because whenever I go into the cafeteria to eat my lunch, Mikayla gives me looks and makes little comments until I'm forced to leave or all of the other girls leave because "they have to do something else". The problem is, my friends, Dana and Nikki, have absolutely no clue what's going on. Now I've resorted to eating in the locker room and doing my homework or studying while I eat. I really don't know what I'm supposed to do. I'm not such an outgoing person and these were the only girls that I was with regularily.
Now, there's another part to the story...
Earlier in the year, when I skipped assembly to study for a test that I was going to fail (History, don't ask!

) I got some help from one of the sophomores, Rebecca. We spent more time together on the school retreat and she's made it clear that she's going to look out for me. I dont' have any older sibling, so she's become a big sister to me.
Now, after the "episode" with Mikayla and Shauna, I'm scared to get to close to anyone, even Rebecca. I can tell that she knows that somwthing's wrong and she's even gone as far as to corner me at luch and ask me about it. I'm just not sure what to do. I'm worried that if I get close to anyone, Mikayla will find a way to take them away from me (she's done it with other girls) or that they'll leave me too.
I'm really not sure what to do about this and if anyone has any ideas, please post. I really need advice on this situation.

P.S. PLEASE don't say to talk to my parents, as they won't take this so seriously and I'm shy at school, so this is a big deal for me.
