So sorry you feel like
I would be furious if something like that happened to me. How very rude and insulting can people be. Did a great job on your self-esteem too I'm sure.
Since I know absolutely nothing about your health system but think you should make someone aware of the pattern of neglect developing. Repeated cancellations, not being notified when they happen and even occur when cca makes appointant. (You may not be the only one experiencing this problem but they won't know if you don't tell them)
You're a great person going through some tough times. Get the help you deserve.
