Been there done that many times.The thing to remember is this.You can make friends here but until you actually meet face to face this is mostly fantasy.Some just disappear with no notice.If you know you haven't done anything to cause their departure then don't worry about it.I've had people online I've talked to for a period of time then suddenly they're gone....then months down the road I might hear from them again.Could be computer problems,could be server problems,illness or something else in real life that's kept them away.Just take life here & in the real world 1 step at a time & you'll get by.
