When I am Stressed

I have no problem sleeping at night at all. Although there could be times due to too much stress I won't be able to sleep resulting to dark circles under eye in the morning but that would rarely happen. Other things that cause me sleepless nights is when something is bothering me or when I worry so much about my family back home. Other than that, I am fine most of the nights. Unlike my friend, almost every night she dreams too much that gives her restless night and tired body during the day.
