I think not showing up for appointments is only justified if a call is made before the cancellation or there is an emergency,of course. Someone else can be moved up if they need an emergency appointment. It's just not fair to other patients. We all want to be seen ASAP in case of our own emergency, and the opening you free up can be given to someone in crisis if the office has enough warning.

If you're so depressed you can't make appointments to help yourself, you really need a psychiatrist to get your meds adjusted, not a therapy appointment.
