Prepare your mental health support plan for Tuesday / Wednesday now. Who will you have on speed dial? Will you be watching results with friends, or judiciously filtering results through social media etc.?
Regardless of outcome, it will be a mentally taxing time. You may be exhausted, anxious, struggle to concentrate, have trouble with executive function.
Account for this now and reduce obligations where necessary. Maintain structure if that helps you, or reschedule if it will be too much.
