I'm sorry it felt like she was talking about termination. I imagine that must be terrible. Was she actually, though? Did you ask? Because I think it's possible that wasn't on her mind at all. Maybe she was just checking in. I would think you would be 'allowed' to continue therapy after stabilization. I guess getting insurance to pay might be an issue, but I wouldn't think T would unilaterally decide that stabilization=termination.
I'm sorry you feel badly and hope things start looking up soon.
