People who have depression often have trouble sleeping. They wake up early morning, look at the clock, and never get back to sleep. Of course that happens to non-depressed people also. I once went six months with severe insomnia, when I wasn’t depressed, and did much research on the matter. One very simple suggestion made in a book made all the difference to me.
It was to turn the clock to the wall. I was one who always wanted to see what time it was when I got up to go the bathroom, woke up for no reason, or in a semi-sleepy state glanced at the clock and then went into a panic that I would never get back to sleep…and saw hour after hour pass by until I woke up exhausted. Now when I wake up, I have no idea what time it is and no stimulus telling me, “it’s almost morning and your sleep is over.” I’ve always had some trouble sleeping and was obsessed with what time it was at night. Now, I am getting the best sleep I have in years. Of course, I have the alarm set so I don’t oversleep. Maybe this will work for you.
