I hear you Krazibean. I often think those kinds of thoughts too, like, if she really cared about me, then she would X, Y, and Z. Lots of testing the relationship. And breaks are hard any way you look at it -- I tend to emotionally distance around them, but different people handle them differently. People post here about them all the time so you know this is a pretty common feeling.
In fact, someone else posted recently something helpful on this topic. Their T was leaving on vacation, and they going through these same types of thoughts. I thought the discussion was pretty enlightening, like how you have to catch yourself with every logical leap and challenge it. I will try to link to it.

From what you've posted, it sounds like she's really focused on her own self care, and that it, objectively, has nothing to do with her clients. Like maybe she's realized she's overly stressed out and she just needs to take a total break to get herself together and so she can be helpful to her clients when she gets back. I know it's hard to not feel like it's abandonment at the time though...hang in there. I'm missing my session next week because I'm the one going on vacation, and I still sort of feel like I'm the one being abandoned! The feelings are real, even though they're not very logical sometimes.
