Friendship drama

Hiiii! So i've been feeling a bit down lately bc of friendship drama. It started when my friendgroup of six split up. Long story short, two of the people in the friend group were really bad to me and another girl and they 'manipulated' the other two to beliving it was our fault. Me and the 'nice' friend started hanging out with two other people. The 'manipulated' girls eventually broke up with the mean girls and started hanging out with us instead. Now here's where the difficult happens, because the 'nice' friend suddenly started ignoring and ghosting me. And the worst is that she started hanging out with the mean friends and left me with the people i don't know that well! We go to the same school, and mind you that i started in the class later than everyone else so they all know eachother well. After summer is our class splitting up and i'm SO afraid that i'm going to be alone! What am i supposed to do? And what should i do to feel better because i've been feeling so bad about myself in all of this? And just to be clear that i'm so gratefull for my current friendgroup that has been helping me! Hope this story made sence and that you have a great day! <3
