<human>: I met this woman on an online game when I was 11 or 12. The older I got, the more we spoke. Later, like the curious teenager I was, I started asking a bit more personal questions (with respect, ofcourse). Over the course of 4-5 years, both of us had gotten to know eachother. I was depressed back then, and I'd often talk with her about my problems. I'd also cheer her up if she was feeling bad. We'd also talk about other things. You know, stuff like science, hobbies, basically anything. She had anxiety (is that how to say it?) due to a few things which I'd rather not share here. Basically, we'd just talk everyday and one of us would cheer the other one up if he/she was feeling bad. She knew me better than anyone else did, and I was the only one she trusted with her personal things (and her therapist, ofcourse). In short, we were REALLY good friends. 

It's been close to 9 months. She basically "disappeared". She doesn't log into the game anymore, she doesn't reply to emails anymore. I'm afraid something might have happened to her, which I don't know about. Before you guys think I'm overreacting or that she's not a she or whatever, I can assure you neither of those are the case. We were really close.

Give me a shortened version of the text
<bot>: Met someone on a game 4-5 years ago, we were basically really close friends (we both knew a shit ton about eachother). She's suddenly gone, don't know what to do.
