Nell, an important rule is to post any thoughts you have on answering emails etc before you do it, even if it takes a while to get an answer from someone. That way you won't be so emotional once you do send a reply and as Cas said he is feeding of your anxiety and we can't have that happen.
I don't do anything before I run it past my friends here. This has put me in greater control of myself and the situation. I am sure others would agree.
