I don't know what to do

Hey everyone. I'm a 10th grade highschool student. I had a group of friends I was very close with in Middle School. We were in contact for a long time in High School. But last year, at the beginning of 10th grade, they all of a sudden stopped talking to me. We had a big group chat and one day they just all left the group. They didn't even tell me anything. I called them and texted them, only 1 of them said anything. she said I'm not the person she used to be friends with and that I'm a very different person. It hurt me a lot. At that time, I was struggling with not having as much money, my parents were getting a divorce, and I wasn't doing very well in school. But this hurt me more than anything.<br><br>I don't know what to do. I'm not a bad person. I'm not a mean or rude person. I don't know what did I do wrong. After they left, I felt empty. I don't have any friends now. I have a little bit of a friend. We're not close. But I don't know what to do. I don't know what happened between them and me. I don't know if they will ever want to talk to me again. I don't know if they're even friends with each other now. I'm just so confused. I feel I'm not special to anyone. Not even to my friends at that time.<br><br>I just wanted to talk about it. I felt releaved to talk about it and to let it out. I would love to get an opinion or advice if anyone has been in a similar situation.
