I feel you, so much. I will soon have to go three weeks without my T! Two weeks over Christmas was kinda hard already, but at least I had some distractions because of the holidays and going away for a week myself. Now, I'll have nothing. Just three empty weeks with nothing to do but thinking about T.
Thankfully I'm prepared to mention this in an e-mail and hopefully also next session. Maybe we can still have contact via e-mail.

I wish you all the best for this tough time!
