<human>: Can you summarize the given text in a few sentences?

I had the best friend in the world that made me happy every day, I felt like there was at least one person who genuinely wanted to talk to me and know how my day was going. We talked every day and everything seemed perfect.

Every so often we had our ups and downs, I caused a fight last week and I think it was the last straw for her. We barely talk now, she says she's busy but I feel like mostly she's just avoiding me. I'm desperately trying not to make things worse by saying anything I'll regret, I'm trying to give her her space and hoping she'll get in touch. But it feels like everything went out of the window in an instant and it's making me miserable. I want my friend back, I miss everything we had.

Maybe nothing can be done and maybe it'll never go back to the way it was. I just need someone to talk to about it or someone to listen.
<bot>: I caused a fight with my best friend, I don't think they want to be friends with me anymore, I don't think it can be fixed and I don't know what to do.
