i just got kicked out of a cherished friend group and i dont know what to do

i just got kicked out of a friend group a few days ago and i don’t know what i did wrong. i’ve been rly hurt so i know i need to talk to someone, but everyone seems to have turned away from me. can anyone give me some advice on how to win them back or find someone else i can trust? i think they resent me because i tend to be very energetic, and now i’m afraid to show my face in school because once they unfriended me everyone seemed to. i don’t know what to do. the worst part is i have been feeling them pull away from me for the past six months and i have always been excluded but i thought it was nothing and now it’s like a fountain of emotions flooding out and i just am so lonely.
