I'm having severe anxiety.

I don't have a pdoc appointment until April 18th. I asked to be put on a cancellation list to be seen earlier than the 18th. Do you think that means my appointment for April 18th was cancelled?

I can't call back until tomorrow, so my anxiety is so high and I don't think I'll sleep tonight. I made the cancellation list thing at like 11am today, but I didn't realize this possibility of my April 18th appointment being cancelled.

I need to ask tomorrow, but I'm still having anxiety. I want to be able to sleep. What do you think?
