I am not particularly concerned with security by email. The ones I see are sole practitioners (important because I would not want to deal with office staff having access) and I don't send my social security number to them in email. I also write regular letters so if something was of concern like that - regular mail would be my choice. Putting things in writing of any form have security problems so I don't consider email to be the super hysteria area for me.

Also I don't usually look for the therapist to respond. I do better when I tell her not to do so. Usually it is that she talked in the first place that leads me to write. I think better in writing - when talking to the woman it can seem like my brain is mired in sludge dumped into cement.
