Let your "friends" know? Get real... If you considered them a friend you wouldn't make a post saying you're leaving because if they were friends they would ask you not to. If you're perm silenced your leaving doesn't seem to matter anyway. Therefor, it's for attention not to let anyone know. The first step is accepting when in denial.
I don't judge anyone. I call it how I see it. I don't need to "know" someone to spot out an attention seeker When you see a cashier in a store, you don't know them, but it's obvious that they are a cashier right? Mmhmm Goodbye.
