It could be the onset of the Winter Blahs. Experts suggest sleeping a bit more, eating healthy foods and exercise. Or perhaps you have a lot of work to do that isn’t interesting (papers, reading, etc.) In this case, try to find a little time to do something you really enjoy. Having even a small choice in what you do can help lift your spirits. If you feel your lack of interest goes deeper, it could indicate the onset of something more serious. BC Counseling Services can help you determine if this is something you should get help with.
