Ok so you have told a few lies so that your T will be more worried about you than needed. I see why you don't want to tell them you've been making things up or exaggerating as that would be embarrassing and humiliating but it is an important step forward if you can admit it.

I'm not gonna say that's ok because well you know it isn't ok to manipulate people with lies and your right it is a behaviour you could do with getting to grips with.

Good news though you have been really brave by admitting this is what you do and i utterly respect you for that. The important thing is that you are acknowledging that this is not really acceptable behaviour to yourself and are accepting that in the long term won't do you much good and that you need to get a handle on the behaviour as not to jeopardise future relationships because it will.

I hope you find the words to raise this issue with your T as admitting maladaptive behaviour is the first step in conquering it. Then you can get help for something that you need help for at the moment as well which will be a much more productive use of therapy for you.

Keep us updated on how it goes.
