Thank you Jan.
Yes, this is something I am working on - and I think you are right that it is fed by my perfectionism. But I also have a LOT of demands from my bosses. The problem is that, when I am told I have to do something, I assume I *have* to do it. Other people seem to feel more able than I to say, *Sorry but I can't* or *Sorry but I didn't have time*. I always feel I ahve to meet the deadlines. Perhaps this current experience is going to force me to behave differently. But that in turn makes me feel very uncomfortable.
