I don't have any advice, but I can relate to saying things impulsively without thinking it through. Even worse are the impulsive emails I have sent - emails that seem so urgent at the time, but if I waited a day or 2 I would realize that it would be a better idea not to send it. I've sent a bunch of emails to my professional association, doctors, and union when I was unwell and trying to convince them that I was ready to have my nursing license back. Long emails, explaining everything, to just make them understand. I think all I accomplished was making myself look more unstable. I'm better about it now, but I still feel like sending (or actually send) emails at times when it's better not to.
