I hope you're able to go back and talk to your therapist about all of the things that are bothering you about this. My therapist is unable to give me an official diagnosis, but she did mention hunches that she had when I first started seeing her. She left the diagnosis to someone who is qualified to diagnose, so it came from a GP. Although my T probably knows a lot more about what diagnosis I fit into than my GP does, she was careful to discuss the way I was behaving, which fitted into certain categories, without officially diagnosing me.

If it was just a hunch your therapists had, perhaps she didn't think it was her place to suggest something that she was unsure about. She may have thought that other things needed to be ruled out first too. It sounds like you're imaging all of the worst case scenarios. I do that too and at the time all of the worst possibilities don't feel like they are silly things to worry about, but what could very likely happen. I still worry now, but I can tell you, every time I've worried about the sorts of things you're thinking now, it's been a whole lot of stress over nothing. If your therapist is good, and you have a solid relationship, she's not going to leave you. She was trying to help you with the replies she gave you too. That doesn't sound to me like the type of person who is planning to go anywhere just yet. I know it can be hard when it's been a gap of two weeks though. It's easy for negative thoughts to take over in that time. Hang in there!
