I'd avoid melatonin if you're prone to depression-- it acts as a slight CNS depressant.
Try a search for "DSPS" and find a few good articles on it. The best thing for your situation is this blue light alarm clock, which is expensive but works wonders:

can you elaborate on this a little more? what does it do and why does it work?
This is going to be a little incomplete:
Sleep-promoting hormones are released by the pituitary gland, and the way that the pituitary gland knows to release these sleep-promoting hormones is when light hits the retina, which then stimulates a bundle of neurons called the suprachiasmatic nucleus (SCN). Whenever light hits the retina and stimulates the SCN, the brain inhibits the release of these sleep-hormones and essentially tells itself "Don't sleep." On the other hand, when light doesn't hit the retina and it's dark out, the brain allows the release of these sleep-hormones and allows you to fall asleep.
Think back to an all-nighter that you pulled at some point. You will notice that it was much easier to stay up all night in front of a computer writing an essay than it was to read a textbook to cram for an exam. The reason is that the light of the laptop screen was hitting your retina all night, which told your brain "Don't sleep." The textbook could do no such thing.
It turns out that these neurons respond mainly to blue light (like the sky). Unfortunately many of us fuck up our biologically-ingraned ability to sleep at the proper times with artificial light from lamps, from TV's, from laptop screens, and this throws our circadian rhythm out of order. When it is thrown really out of order, to the point that you are going to sleep at 7AM or later, it's known as DSPS. People with DSPS--about a quarter of the population--usually struggle with it from adolescence onward. Ambien, ativan, and other sleep aids are generally useless in these cases.
The thing I posted is basically a blue light alarm clock. It normalizes your circadian rhythms by shining a very bright blue light in your face in the morning and entraining your sleep-hormones to start releasing and inhibiting themselves at the right time. In my case it has been very effective in normalizing and maintaining my sleep-wake cycles, as it has to many reviewers on that Amazon page, and is well worth the $150.
