I have been annoyed by t's that insist I needed to think positive and that that will fix everything. It's bothersome that they don't seem to understand how difficult that is. While it's a great concept, it doesn't work for everyone (actually, I don't know anyone personally that it had worked for). It's very invalidating to me, and I had reacted in a similar way when a t pushed the issue.
I don't think what you said was rude, it was simply the best way you could communicate your frustration at the time. I would bring this up with your t. If it helps, bring in your post and show him. Hopefully talking about it would clear things up. If he is not receptor to that, perhaps finding a newt would be in order? Or maybe look at and talk about what's behind the resistance to therapeutic interventions if you find yourself unable to do anything at all to pull out of the rut. I know I go through periods of time where I feel like I'm simply saying no to everything my t suggests (including things that have worked in the past). That's usually the time we talk about what makes it difficult for me to engage with anything...
