This would be a really big issue for me too, old waiver or no waiver. If you step back, does your T have a reason to be very worried about you? If not, you have a decision to make between letting her repair the relationship with you and both of you working on that or terminating. If a new T did this to me, I wouldn't stay. If this is a poor judgment call in an otherwise steady good relationship, I would roll up my sleeves and get to work saying how I feel. My T makes mistakes, and they spook me, and set me back trustwise. They also make me examine the level of my own dependency/ attachment, that I cannot leave even if I think I should.
