You should have been given some important dietary guidelines with respect to avoiding certain foods that contain purines. The metabolism of purines leads to the crystals in the joints that are the hallmark of gout. The main things to avoid are red meat and certain seafoods, whereas dairy is a good thing. A very newly published study links gout with red meat consumption, in particular. Here's an overview site: http://www.podiatry.curtin.edu.au/encyclopedia/gout/

There are also a couple of drugs that encourage the kidneys to flush those salts out in urine (colchicine, allopurinol, and some newer ones). Really, it's a routine medical treatment.

I'd consider gout to be quite independent of the mood problems, although there are certain symptoms that are possibly shared. Gout can be depressing, certainly.

You should be under a doctor's direct supervision for this. Acute attacks of gout can permanently damage the soft tissue in the joints. Analgesic anti-inflammatories can help with some symptoms, but you need to treat the high blood uric acid concentrations directly.

Good luck,
