I feel you! I had to leave town for a little more than 3 weeks, but it actually ended up working out well b/c my therapist had to leave for a little less than a week at the same time.
But anyways, my last sessions was on June 7, and my next one will be on July 1 (in exactly a week tomorrow!) Ever since our last session, I've been counting down the days 'till July 1. I've sent her one email and called her once to schedule my July 1st appt. I don't plan on contacting her again until the 1st, but I am excited for my upcoming appointment.
Anyways, hang in there! I have a week to go until I see mine after almost a month without a session, and it def seemed like SO long (still does) until I see her, but I figure if I got thru the last couple weeks, then one week isn't that bad.
But yeah, maybe you can write out letters to your T (you don't have to actually send them) saying what you might say had you been in session. That might help. Good luck!!
