It’s very possible that she felt nervous or something too.
She was nervous as well. The fact that I was nervous was not the problem, but the way I expressed it was. When I'm nervous/anxious I tend to take it out on others and basically try to drag others down with me and when she's nervous she very much keeps it to herself.
I met my internet best friend this summer and I think that's how she felt about me.
We had an okay time together but our friendship doesn't feel the same anymore (in a bad way) and it's 100% my fault because I was agressively insecure all the time. I was meeting someone from the internet for the very first time and it was also the very first time I left my country completely on my own.
However, that trip and meetup changed me a lot for the better. I feel like I matured a lot after that.
I hope she will forgive me and give me a second chance. I will also very much understand if she doesn't.
Edit (Oct 24 2025): I told her my feelings in July and she said that she has no desire to continue our friendship and I haven't talked to her since.
I got hit by 2018 nostalgia from seeing this.
