I don't really know how to start this post, but all I know is I need advice or some sort of help. My best friend and I have been friends for 4 years (we became friends in 8th grade, and we are now sophomores). As far as I know, we've been on great terms, and no arguments or any dilemmas have shown up for a long time. We also don't have any unsolved issues or grudges. Fast forward to January of this year, she tells me she needs to go online for the second semester of the school year since she's going to get surgery on her knee and won't be able to get around school very well. I fully supported and mentioned that I also planned to go online for the second semester because in-person school had made me develop really bad anxiety and depression. She got super excited, and really wanted me to do online with her since she doesn't have other friends, saying how fun it would be for us to hang out and do all kinds of things together. Later on, something happened with my family where I did need to actually go online for my safety, so everything worked out just fine. We were having normal and funny conversations every day, and everything was going fine, until February 13th. We were just having a normal, silly conversation about wanting to move schools and get a fresh start since we hated the people at our school, and then she stopped responding mid-convo. I thought she was busy since she usually does things like this, where she disappears for a week or something because her family is very chaotic, but even during that time, she always finds time to talk to me. I kept texting her like normal, hoping she would respond, but soon the week turned into weeks, and then now it's been 3 months. I got really worried the whole time and thought she got hurt or kidnapped, often texting her and asking her if she was alive, both on text and on her TikTok account. Finally, on April 12th, I scrolled on my TikTok and checked the comments section on one of the videos, to find her in the comments section responding to something. I was immediately confused and went to confront her, stating my confusion, and when I went to the video (it only had like 23 comments), her comment was deleted by her. This happened in a matter of MINUTES. I was hurt and confused, and even a friend of mine earlier on, who I talked to about this situation, stated she might be ghosting me, which is true. I finally sent her one last message, telling her she doesn't have to be a friend; I would just like an explanation as to why this is happening. She never responded, didn't block me, or unadd me from any socials, which I find weird. It's now been 3 months since we last talked, and I've been trying to let her go, but I keep remembering all of our good memories together. Is there something I'm missing, or did I do something wrong? Please help, I'm just so confused and hurt.
