That must have been quite a disappointment for her cancel at the last minute. I can see it triggering really bad emotions. You might want to give your pdoc a call if you have one. The symptoms seem to be rather serious.

Do you have anyone with you? Or could you get someone to come sit with you? If not, you may want to call an abulance if the symptoms don't lighten up soon. I worried about you. Please take and know that this will pass, even though it may feel like hell right now.
