Maybe you should show her the pictures instead. Placing them on her desk is a little bit passive aggressive and talking about how you feel will probably be more healing than simply informing her.

I'm so sorry you're going through this. I would have a hard time too. I mean hell, when I was facing a two week break from seeing my T constantly but still having contact with her, I was a sobbing mess. I was also facing other stuff too, but I was still very distraught thinking about leaving her for that amount of time. If she were to leave suddenly, I would be completely heart broken.

I don't think crying is something you need to "control" either. If you are more weepy right now, that's okay and that's good.
