Maybe another way to think about this is that you know yourself and you know your own patterns and behaviors. I think that's a good thing. Everybody has limits regarding how much they can "trust" themselves, and professionals know this.

That's why the diet expert says not to keep chocolate muffins in your desk. If they're there, you'll eat 'em. Or why the doctor recommends a physical therapy regimen with an actual person instead of just sending you home with directions.Or why people trying not to drink don't go to bars with friends.

I think a big part of "trusting" yourself is knowing your limits, behaviors, patterns. It's a lot better than keeping the muffins in your desk, swearing you won't eat them, and doing it anyway time and time again because you can't accept what you know about yourself.

Telling other people helps keep you accountable. I'd be as honest with your T as you possibly can.
