Endurance

I have failed once, i can't fail again, this is my last chance. My chemistry lecturer allowed me to retake my subject and adviced me to work extremely hard, needless to say... now all the hard work and pressure came all at once, from parents, from lecturers, from friends and from myself. Can i take it? I guess i don't have a choice! As my dad always say, delay gratification... hope my body and soul can take all this! arghh!!!!
