I do not like what your T said about the tabs lined up and think this needs to be discussed next time you see her. But I do agree with what she texted you about texting. I think texts are very prone to misinterpretation--even worse than emails, which are prone to that themselves. Perhaps if you need to contact her, don't use text or email, but use the phone? That way fewer misunderstandings. You told us she didn't want you to send her texts and emails, but what is her phone policy? If she is so critical of texts as being prone to misinterpretation, then it seems she would prefer to receive phone calls?

Sorry you got that "tabs lined up" response. I agree with what others have said--that is way too late. I agree with what gelfling wrote about having a plan. If you get to such and such a stage, then you do X (e..g call a crisis center). If your T isn't willing to handle emergency situations, she should be frank about it, and give you other instructions for what to do in an emergency.
