I had a couple of beers once before a therapy session, mentioned it, and my T got very annoyed and demanded, "is there any point in even having this session?" and I replied "yes" and we had the session but I still felt she was annoyed. I didn't ever do that again.

I guess the biggest upset I had was when we were working hard and then she sniped, "Not if you do what you usually do!" and almost felled me in my tracks. I took it as a criticism, that I was not able to change and kept doing that sort of interaction the same, wrong way. It took me all weekend to realize that she was "warning" me and that is was in fact time to fish or cut bait.

I tried from then on to not look at the other person's irritation but at the possible pearl forming? :-) Only a person who cares gets frustrated with you and, usually, they have a point. Standing on one's head or doing whatever one can to get that point, knowing that it hasn't been grasped before and is what is causing the frustration (not "Me", my behavior) and experimenting with doing "exactly" what T is saying (in my case, the opposite of what I normally did, which was shut down), just trying and stumbling along because it is new and one is sure one is going to die from doing it helped me enormously.
