How long have you been seeing her? Is it possible to find another T with more availability? I'm really lucky and found a T that doesn't have a full schedule (pretty sure she works part time) so rescheduling appointments is really easy to do. I had to go two weeks without seeing my T because I was out of town and that was hard enough once, I can't imagine it is at all easy for you...I think you should maybe start exploring the possibility of seeing someone else and when you first talk with them, as how often they are able to get you into their schedule and how easy it would be to see him/her more often if needed.
