I think the time to call your T is when you need him or her. The T agreed to help you right? What part of, let me take care of things myself and when I don't need you (the T) is when I'll talk to you, is in the agreement?
Sorry.
Patients often feel that their actions will scare a T off. The T understands feelings more than you do... and can help you in ways you can't think of and say things you can't realize on your own. Please call your T before it's out of your hands, and while the T can help you more easily. Sometimes a call or two can avert a crisis situation. Wouldn't that be best?
