How come you're still up ? Shouldn't you be asleep by now ?   I've been having a hard time sleeping lately .   As far as I know , insomnia is usually caused by stress . Are you stressed at all ?   Well , I'm really worried about my grades . I didn't think this course would be so stressful .   You're a good student . I'm sure you can do well . What you need to do is to relax .   You're probably right . I just wish it were that simple . How can I stop feeling so anxious all the time ?   Taking a yoga class or learning some relaxation techniques can help you cope with your stress .   I don't really have time to learn anything new . I need to spend my time studying !   You need to take some breaks throughout the day . Studying all day isn ’ t very usually effective .   You ’ re right . I usually end up staring at my computer or checking my email instead of doing my work for class .
