I'm having a similar issue with my t. Not with extra appointments, because they are impossible to get, but I am allowed to call or text my t when I need to if I am feeling like SI'ing and stuff. I contacted her a few times this week. I probably should have another time or two, but I always feel like I shouldn;t be bugging her when she's not at work.

T has repeatedly said to contact her whenever I need to. I think your t probably knows you well enough to know when you REALLY need help, and would not offer to provide that extra contact if he didn't want to or didn't think you need it.
