I've not long finished an 8 week one to one course of it mate and it's been great. I never really expected much from it because I'm a bit of a knobhead and rarely follow these things through properly, but I actually did everything that she asked of me in terms of the bits of 'homework' she gave me and I was brutally honest for once about my issues and that helped massively.
I've had similar things before but always held back bits and pieces cos I'm not really a big sharer of my thoughts and feelings, so unsurprisingly any treatment hasn't had the desired effect. Don't hold back mate, if there's something bothering you that you think isn't of relevance then get it off your chest anyway, I was surprised at just how many little things were all linked together.
Good luck with it, hopefully you'll benefit from it as much as I did and if you want any advice about what to expect etc. then feel free to message me.
