I've had severe depressions in about the past four years. I've been having mood swings about as long, with the depressed part looking like this: my alarm clock wakes me up, I oversleep or wake up feeling anxious and nervous and tired. During the day I can hardly concentrate on anything, most of the time I just stare at the floor or outside or whatever happens to be around, I have headaches or other aches I can't explain, and I feel sick, I eat more than normally, feel worthless and hopeless and unmotivated, and I either cry myself to sleep or barely sleep at all until morning, and I'm scared of what I might see in my dreams.
