The difficulty of surpassing someone

How do you get over someone? The thing is, I had a friend, and it was a really good friendship. Unfortunately, we couldn't see each other in person because we lived in different places, but that didn't stop us from playing games every day. We had the same tastes, and we talked every day. But one day, this person started to distance themselves without any explanation, and they became more and more distant each day, until one day my messages stopped going through, and I realized they had blocked me. Now I can't get this person out of my mind, and I ask myself every day what I did wrong in that friendship for them to distance themselves.

It was such a beautiful friendship. She always talked to me, without exception, every single day. She always worried about me, and if I was feeling down, she'd try to cheer me up, something I was always grateful for. I'm so confused because I don't know what I did wrong for her to block me, and I can't ask her anywhere else since I never asked for her Instagram or any other social media because I forgot. All I have is her WhatsApp number. I was hoping she'd say something for my birthday, anything at all! But she never did, which makes me a little sad because, as I've said all these times, she's my best friend, or at least she was. I don't know what I did wrong. I was always there for her, I never made her feel bad, and if one of us had to be angry with the other, it should be me. She had a certain attitude that bothered me, and I told her so many times, but she still did it. When I told her again (that this attitude bothered me), she would say "okay" and apologize. I accepted them, but I don't think they were ever real apologies because she would go back to that attitude that bothered me so much.

 I remember crying a lot when I found out he had blocked me because I really felt like he understood me, that he would always be there for me, but unfortunately that wasn't the case. I was always surrounded by people, but deep down I felt alone because everyone else had someone else and I was alone. This year, another very close friend and I have been somewhat distant, so that feeling of loneliness only grew. I kept this feeling to myself for quite a while because I honestly thought no one would care.

"Okay, I don't understand, alright? I always try to change, but I've gotten used to everything always being my fault. I want to be the best for you, but I always disappoint others, I always make them angry. I'm used to having to apologize for everything. If you don't like that, I'm sorry." She was having problems at home, and she had recently lost a friend. I always tried to help her with that, and because of this problem, she apologized for everything, and when I say everything, I mean EVERYTHING. That bothered me because I didn't think it was necessary, and besides, she exploded very easily. It was impossible to know how she felt. She could be happy and then sad, which made it difficult for me to tell her anything because I was really afraid of saying the wrong thing and making her angry with me, since in a way I think I depended on her. I had lost the desire to talk to others because they reminded me of that loneliness I felt. They reminded me that they had someone better, a better friend. All my female friends have their favorite friend, and I'm not one of them. Sometimes my male friends either didn't pay attention to me, ignored me, or simply didn't take me into account. She helped me forget that. She made me feel that for the first time I was someone's choice, something that never happened to me with anyone else, since I always felt that they could choose anyone else before me.
