If you feel you need to do something I suggest you sit in a quiet place.
Breathe in for 4, hold for 4, breathe out for 8 (or up to 8 if you can't quite manage it).
Do this three times.
Breathe normally for a bit then repeat if required.
This should help to relax you.

Call the doctors first thing tomorrow if you can and tell them its urgent.
Don't take the pills.
