Am I wrong?

So it happened that two of my boy classmates forced me to cheat. I felt like I should do it or else they wont stop me. So I helped them answer their exams and they made those two boys made a group chat which consists of Two boys, me and another girl which is my bestfriend. The two boys suddenly just added my bestfriend. And we cheated, while I was passing the answers to them. I accidentally sent it in our class subject group chat which has a teacher on it and I was caught red- handed. I was trembling when that happened. Legit I was really trembling af. I didn't know what to do. So I told some people about it because I was really trembling af. I told my close friend but she didn't really treat it as a serious matter. I told my cousin and I was relief she listened to me. But when that close friend didn't really mind what I said to her, I felt horrible. I was crying to the point that I can't breathe at that time and she will only say that. So when the next time she talked to me, I had this grunge and I ignored her messages but I know I can't always ignore her. I will talk to her when I think it's time. I also did something horrible which I also ignored my innocent friend. He keeps texting me but I don't have the guts to text back so I also ignored him. I know it's wrong. And I really regret I'm so sorry. I don't know how to go back things the way it was with my online friend.

How should I handle my close friend that I ignored because she ignored my problem? How can I go back things the way it was with my online friend which I also ignored because of my selfishness?
