Stop googling. Think about your T, not the internet.

Your T was talking about things you can do to help yourself when you are feeling anxious. She was talking about breathing, etc. Email wasn't part of that conversation. Abandoning wasn't part of that conversation. She is going to work with you on skills to help yourself when your are feeling overwhelmed. That's a good thing.

Your T is listening to you and working with you so that you can comfortably communicate what you need. Doesn't sound like abandonment, does it?

Get off the google. You're just stressing yourself out with "what ifs".
