I’m sorry you’re having so much difficulty! It sounds like this wasn’t handled properly by the facility nor the therapist, but it is hard to know their policy and why it was handled the way it was.
I’m sorry you’re feeling so bereft, and I would encourage you to ask the facility for recommendations for other therapists. They at least owe you that. I would also ask them for information about groups, as I do think individual therapy should at least be supplemented with group therapy — if not entirely replaced by it.
The reason I suggest this is because groups meet very regularly, usually at the same day and time, even if a few people don’t show up the group usually runs because there are enough members there, and facilities tend to pay more attention to the fact that the therapists isn’t showing up for 6 to 10 people then if he isn’t showing up for one.
I also think group helps you learn things about yourself from different perspectives, while giving you a chance to flourish in a stable on-going environment.
