Losing My Best Friend and Feeling Lonely

I don’t have a best friend anymore. I lost her because we could only talk about my problems. And every time we tried to talk about anything I dropped the ball. And it was my fault, she just said we would be better irl friends but not online friends. I feel lonely. I miss having a best friend. Someone I can just talk to about my day. It doesn’t even have to be about my problems. Just something causal and fun. Or light-hearted. I never meant to hurt her, or make it all about me. But I did and it wasn’t healthy. I just wasn’t the right person for her. But sometimes I think something is wrong with me. Because I have all these problems and just want to conquer them but it takes time. And I just I hope I can sometime soon. I just miss her sometimes.
