Ah, ok. Yeah, schools and places like that can sometimes not be ok for singing stuff in. But you can do it by yourself and here all you want!
I have a couple "faces"/alters that hurt other "faces"/alters, and that can imitate voices and even act like others! It can be really hard to figure out who's who sometimes. And I can also understand the frustration! I hope she can realize soon that it's not her fault, it's not in her control, these things happen and she's not alone, and that there's explanations for these things happening (like having DID). I'm glad that at least Alexander doesn't hurt anyone in the real world though.
I hope you don't get in trouble for talking! You should be able to talk about anything you want! Especially here. This is a very very safe place. I hope Ace and Steve will indeed be able to stop him. (If you don't mind me asking, who are Ace and Steve?)
I've had "faces"/alters talking to people like my dad and the people don't know they're not talking to me, too. So you're definitely not the only one who's had that happen to them!
