Yes, depression can cause this ((((home))) There are lots of things to try, naturally, to help sleep. You do right to get up out of bed if you can't fall asleep after 30 min or so of trying. Is it cool/warm enough? Are all the lights out? Is it quiet? Can you calm your thinking, and think only about peaceful things? It isn't a good thing, from what I've read, to watch tv...too "exciting"... can you take a calming bath, drink some milk, or do stuff like that to help?
