I tried to keep it short but I think I didn't manage...

As last week I was not sure if I can come on Tuesday, T scheduled me for Thursday and asked to let her know whether I can make it on Tuesday. I could but after the session I realized that I had no idea if I could come also on Thursday as I was scheduled, as well. Thus, I sent an e-mail to T. In the morning I got the response that, we'll have next session next week. I was pissed a bit but immediately just responded "Ok". But it was not ok as I really hoped that I could come... It was like a good trigger so I barely managed to keep myself in one piece but when I eventually calmed down, I sent T the e-mail to simply let her know that I was struggling a lot but was okay and calm now, so just to simply let her know what was going on (we agreed to do that) and it absolutely wasn't my intention to ask for the session when I was writing it...Somehow my T misunderstood the fact that I'm okay with not coming tomorrow and sent me a response:

Ok, you can come tomorrow at 3.30, is that ok?
Sorry I don’t qualify in mind reading….. You are invited to ask me frankly ..:-)
See you tomorrow?

And it just really pissed me and again threw me out of my window of tolerance, like I am a burden and that T is annoyed and frustrated with me and now there is just no way I could come tomorrow. Not at all... But what should I do in this case? I could ignore this e-mail and simply not come (not nice) or I could respond something (e.g. what??) to let her know that I won't come... But honestly I'm afraid that she'll just think that I am extremely moody and am bothering her without any reason...
