Online Best Friend Disappearance

I was in a close 5 year online friendship where we grew an extremely deep bond and daily contact and long wonderful conversations. She built most of her community on the foundation of mine for streaming on Twitch and on Discord. She told me I was the first and only person to ever make her feel safe online and showed her that online could actually give her so many beautiful friendships. Over the last few months she began bailing on plans frequently which was strange for her after 5 years. It started to happen around the time she had a falling out with a mutual friend who was accusing her of things she had no proof of. Any time I would bring up the bailing she would passionately reassure me. That she cared deeply for me, that she would fly to Canada from Florida if there was ever an emergency. Even up to the last day she told me if I ever needed anything to never hesitate to reach out because I'm extremely important to her and I was always there for her. I was beginning to have major insecurities due to the bailing but I did know more was going on behind the scenes she wasn't telling me. She told me she was tired 90% of the time these days and things would get better once she balanced things out. She told me weeks before for the first time that I'm her best friend. For the first time in 5 years. Passionately too. Seemingly surprised I didnt know that about her already. She told me once on a phone call 3 weeks before she left that she'd thought about leaving before because she didn't want to hurt me anymore. I didnt take it that seriously though as I should have.

Well 6 weeks ago I had a breakdown and I sent her a message. No insults but in a disappointed tone telling her if she was going to keep bailing that I needed to put energy into people who put energy into me. I questioned her words, her friendship, how much she cared. But it was out of hurt. Not malice. And then i got scared and bombarded her on the last day. Just trying to get her to respond and she disconnected her phone number. I was the only online contact she ever gave her number to. She insisted I had it to that I had more access to her. I had never ever done anything like that to her in 5 years. I was just hurt and I figured she'd understand. I sent her a few heartfelt messages and then wrote a beautiful letter in a word document and sent it in discord DMs over the first 2 weeks of ghosting then stopped messaging her completely to give her space.

4 weeks later she finally popped back up on discord but this time she unfriended every mutual contact, left every mutual server, and deleted her own server. These were people she loved that she had no conflict with what so ever that she talked to regularly. She did this meticulously over the course of 4 hours.

She left a message to a friend that she seemingly sent to be directed to me. It reads:

"TY for the kind gestures, good memories, and everything🩷 I always hold these close. If anyone asks you can say this on my behalf to them. They're included. I just don't have a chance to message anyone else rn🩷 take good care of yourself and everyone too🩷"

And then she deleted her server cutting off contact with everyone before my friend could respond due to her discord security settings only allowing messages from friends or people in mutual servers. She never blocked anyone and I'm still friends with her on multiple platforms but those accounts seem to be dormant. There has been absolutely zero activity from her on everything. Gaming consoles, social media. Its soo eerie. I dont understand whats going on and why this happened but we have no way to contact any of her personal friends, family, or get a wellness check for her. I'm just really worried but I still feel like I'm in limbo wondering if she'll ever return. Any thoughts on this would be appreciated
