i found it immensely useful, i spent 3 months in the Priory Hospital doing CBT andf Psycotherapy, all very useful, although when i came out it was hard work to put everything you learn into practise, i tried all at once with all the different things you learn! didnt work out. The biggest thing i founf going to the Priory was meeting the other patients, i met some amazing people, a lot going through the same as me, and that, knowing i wasnt alone, was an enormous releif.
I now see a one-on-one counsellor, who is using EMDR, which i have no idea why it works, but it does, we have found some very interesting facets of my personality that i didnt know about! But the good news, this works for me, its extremely hard on your emotions and diffucult to work through the tough parts of your life, but it has made a much bigger difference than CBT did.
The just sitting there talking is very good as well, the important thing is to trust your therapist, and i do and that has helped me open up an awful lot.
