In addition to mentally preparing yourself for the challenges of making a change, it is also essential to be sure that you are taking care of yourself physically during a transition period. When things are in flux, you might find that you neglect many of your basic needs. 

Stressful events often seem much worse when you are exhausted or hungry, so taking some time to attend to your basic needs by eating a healthy meal, getting some rest, or just taking some time to relax can restore some sense of equilibrium to your life.
