do you ever feel like, just because you havent posed ect and stuff you realise that no one is affected by your absence and people/friendships you thought you made turn to dust? the fact that peoples accounts get deleted and then no one remembers them but you? the waiting that people will notice you somhow and they'll make effort to intteract even if im not? that as more as more i meet people i forget others. and im too scared to tell them im alive. im too late to be their friend again
