What was the roughest time in your life ?? What caused the situation ??

I have had lots of challenges, but the most emotionally stressful time was when I was in a very difficult engineering school. Classes from 8 to 6 three days a week, 9 to 5 twice a week, and 9 to 12 on Saturdays. It was the first time in my life that I had to worry about grades. My girlfriend was at another university, dating other guys. I had no money. Thank goodness for my friends who helped me get through it and for my girlfriend who insisted she loved only me.
