A few months back I had a similar situation- T was on a conference so we missed a session. Before he went he emailed me to check I was ok, which I wasn't. I had to force myself not to call him, so his email came a such a relief. But he didnt respond for a couple of days, and by that time I was in complete meltdown and didnt know what to do. His response to my email was very brief, like he couldn't care less. So I called him, he didnt answer and I left a message (I NEVER call T unless I'm sui). 3 days later he called (from the conference) and he really didnt help, so I cut the conversation short. I was REALLY mad with him, and it ate me for the rest of the week, until our next session. I was thinking similar thoughts to you- that everything is on his terms.

Anyway, I wrote A LOT that week, and some of it I took to T. We talked about it and he admitted that his response was counter-productive and that he could see how I felt dismissed. I still havent found out why it took him so long to call me back, but I HAVE been able to continue on our "path" because he is VERY good at resolving ruptures in our relationship.

I would go back to the next session, tell T how you have felt since she has been away, and see how she responds. I would think she will understand and will be able to give you her take on things, and you can try and re-build your relationship from there. Please don't give up until you have spoken to her about this.
