Something I tell my husband when he is feeling like this is to NOT make any decisions about your life or anything heavy when you know that you are depressed. You can't possibly be logical or rational when you feel so bad. So don't think about anything heavy. Don't watch the news or sad movies. Watch the Comedy channel or a light movie. Try consciously not to get too heavy. If you want, you could write down thoughts that bother you so you can "shelve" it for tomorrow or on a day that you are feeling better. Hang in there!
