Yesterday I had a skype therapy session planned and it did not work out.

It said she was away or offline. Her two calls that came through were dropped by skype within a few seconds. My skype call to her was not answered. I tried emailing then calling her on the phone, but she has not responded.

It took her 5 days to get back to me another time when I emailed her. I feel I can't wait another 5 days now.

How long should it take for her to respond?
