I like this.
I do believe there are times when a T needs to get a bit tough with their client. THIS IS NOT ONE OF THEM.
I also like sarahsweets idea of writing something out. How do you feel about that? Do you think it might help?

As far as full time work goes, I've been stable for a considerable time now, have never had ECT and even so, know that full time work would be too much. And certainly in anything that is stressful. I don't think hers is a reasonable expectation, given your circumstances. You seem to have good insight, so you are the best judge of what you can handle.

About conveying your struggle, maybe write down some basic things that are problematic for you. Perhaps then point out how that would impact a demanding job situation. Be careful though. I don't want you to get down on yourself. You're wonderful just as you are.
