Speaking with Mute Voices

I thought of the expression "falling of deaf ears," but that'd suggest that I'm having a problem listening to people, which isn't the case. It's that no one's telling me anything. Normally such things wouldn't bother me (all that much), but this time it's different, because this time it's the people who I thought could tell me anything that won't tell me a damned thing.

I don't know what to do. I'm worried. I feel like I can't get any words out. And if I try to argue my point to these people, I'll be shot down/ignored/whatever else could happen that isn't them telling me what it is I was promised I'd be told and then suddenly "not in the mood for telling" happens...
