It can work if you work it...but yes it does work alot because we all have faulty thought patterns. But it is work...to sit down and analyse your thoughts. But it is worthwhile too, it can alleviate unnecessary pain. Try Aaron T. Beck web site on cognitive therapy if you haven't already.

When I checked into a mental facility we had classes every day all day. Some people work the program and some people just wnet to the classes and did nothing. It can help but it is hard work.

I was looking for that but were I live they only have one . It's covered under my health insurance...

I find that learning how to "catch, check, and change" thought patterns -- one of the major things covered in CBT -- is difficult for me because I'm not so good at the catching part. But I've found it real eye-opening as far as noticing just how negative my thoughts really were (it was worse than I expected).

I don't know if things like this are particularly Web friendly, but there are some free courses on the Web if you want to take a glimpse at it. Here's one:

It can be pretty ugly when you strip away everything and look into the thoughts that you don't really pay attention to; but feel. I had to really look at what I was thinking about anything anyone said to me. And yeah, they were pretty negative.
It's a real eye opener.
