Don't take the stride out too early. Sorry for the running metaphore, but it makes sense from the point of view that stress will make you try to do too much too fast and cause you to overload. Save as much of your strength and stamina as you can for the last spurt dear. Steady on. You can do this. The worst is actually behind you.We are all pulling for you. HUGGGGGGGGGGGSSSSSSSSSS!!!!!!
