Hey nothing, I think it is good to keep in mind that your therapist was trying to help, and unfortunately it apparently didn't. He was trying to connect with you, and it failed. I agree with Terri that you should communicate to him that his approach failed ? it increased your anxiety as opposed to doing what he hoped it would, inundate you with intense, what you call "scary" ideas and discuss them with a calm composure, showing you that you can separate the FEAR from the idea.
Again, unfortunately it didn't work at the time. But I don't believe he ever intended to scare you in a way that would be malicious. That makes no sense. So just keep communicating with him. Honestly, I think I'd get along well with your therapist.
Keep in mind these doctors have not experienced your symptoms, and there's no established "cure," he's doing what he thinks might have a positive effect and its your responsibility to let him know if it is working or not.
Whoah Brain, that's a pretty intense reaction...
"Best way out is right through" is as ancient an idea as there is. It goes way deep ? and when you think you're at the bottom, it just keeps going deeper.
