Talked bad about friends to each other and now whole friend group against me

I 12F am in a seven person friend group . it used to be a 6 but then we kicked someone out but that doesnt matter . then 2 more people joined . however at the beginning i didnt want them and i thought no one else did . turns out i was the only person but everyone acted like it . from there secrets drama all that stuff came out . i was on no ones side . but if someone asked something i would give info about someone . then people ( including me ) started to feel left out . so we all had a talk . turns out some of the private stuff i thought wouldnt be told to certain people was told . now everyone against me ( ik one acts like it but isnt but still ) . what do i do
