I'm really sorry that happened. I don't think it's a little thing at all. I think it's a big thing. This appointment is really important for you and, as you say, getting to the appointment involved a lot of stress. To get there and then be told it's canceled is definitely a big deal. Plus you were really hungry and that often makes us more vulnerable emotionally. I completely understand why you are upset. I really like your Mom's suggestion about being honest with your doctor about how the cancellation effected you. And it's good you told the office receptionist that too.

I hope you can be gentle and kind to yourself and not beat yourself up! You have every right to be upset about this stressful situation! I hope everything goes well for your appointment on Thursday.
