Lucky for me, my therapist hasn't seen this as a "boundary issue" for me. She has allowed me to email "at will" for as long as I've seen her (2 1/2 years on and off). I've never been bothered by her answering or not answering . .. But to be honest, she has been fine about responding to any and all emails I've sent .. .There have been a few that she hasn't responded to and I haven't been in the least bothered by that. If I wanted to discuss it, I took it to our next session. I admit that I am a person who "thinks" much better through the written words. I can articulate "thoughts" very easily through the spoken word, but when it comes to deep thinking or feelings, I do much better through journaling or email. But that's just me. The fact that she is so receptive to me being able to email has meant a lot to me when I think about moving productively in therapy. . . But then I also know that what makes this world go around so perfectly is that we are all so very different and work so well with such different therapists!
