candy, my therapist has a phone number for messages. He never answers this phone "live", but I know I can always leave a message about canceling an appointment and he will get it, and will call me back if necessary. Why don't you tell your therapist what happened and ask if there is a way you can leave a message for him/her when the office is not open? I am sure your therapist wants you to have a way to cancel appointments as it would screw up his schedule if clients weren't able to do this. Just pose him the question and wait for him to give you the solution. This sort of logistical issue is something that is his responsibility to work out, not yours.

My T does not provide me with his home phone and never gave me his email address (and it is not on his business card). He has never encouraged me to call him for support. And his answering machine message tells a number of a crisis line you can call if having an emergency. I do have his email now since he is also working with me professionally in a non-therapist role, and I sometimes copy him on group emails to keep him informed. Since obtaining his email, I used it on one occasion for a therapy related issue, and he responded quickly with a brief message that was reassuring.

That's my story! Every therapist is different with how much access they provide. My T has firm boundaries regarding phone and email.
