You just have to make a deal with yourself, Hamster. It's not worth going if you aren't going to tell the truth. I do understand the urge to lie, make yourself seem better than you are, or just to get out of being in trouble, but it really isn't worth it. You're paying (or someone is) a small fortune to see the pdoc and T. Think about what it is costing you each time you consider lying. Force yourself to look the doc straight in the eye when you are tempted to lie - for me, that's something I have a hard time doing, lying with a straight eye look. You could get drastic, make yourself tell your doc every time you lie. "Okay, I just lied to you. Let me try this over again." That'll cut the urge down pretty quick!
Hang in there, and keep the falsehoods to yourself. Straight on honest is the the best policy when dealing with people you are paying to help you.
