I hope you got the therapy you clearly need. People drop off the internet for all sorts of reasons. I remember bleeding friends because a platform died. It's just how it is. This can be their lesson learned that you actually need multiple ways to contact your digital friends. If it were me, I would have been oh well too with my kid. Taking gambles like lying about your age sometimes doesn't pay off. Sometimes your parents just up and move. Somehow I survived losing digital and IRL friends because of things I had no control over. Learning to cope with that is an adult skill that you everyone eventually needs.
