I often feel this way when an appointment gets cancelled.....luckily it has only been a couple of times. I tend to take it very personally. About 5 months ago, my appointment with my pdoc got cancelled because of a blizzard. Pretty much everything in town was shut down that day. I was very angry and remember trying to find a way to blame myself for the appointment getting cancelled. Looking back, I can see how silly it was....I have no control over the weather ! I ended having to tell myself over and over that it wasn't my fault and the cancellation had nothing to do with me personally. Don't give up. Call tomorrow and reschedule, and when you do get in, make sure to tell her about what you are feeling. Also, talking to someone that you trust and is supportive between now and when you can get in might be helpful. Take care of yourself and stay safe.
