I was severely depressed a month or two ago, and I went ahead and bought two 2 pound chocolate rich cakes in succession and ate them over a period of 24 hours. Though it didn't kill me, but it was definitely not too upsetting. I still have the urge to just eat huge quantities of sugar, and I am not sure how to control it, but yea it definitely did not kill me or make me sick.

I am otherwise an extremely fit individual (can run 5k in 16 minutes)

Incidentally there are some studies with rats showing that sugar/sweet addicted + cocaine addicted rats prefer their sugar hit over their cocaine hit, and plain sugar-addicted rats when removed from sugar/sweet had opiate-withdrawal like symptoms.

I guess I will need to get this sorted out sooner rather than later then.

Eating sweets does improve mood. There are several known mechanisms. e.g., carbs facilitate amino acid transport across the blood-brain barrier [1], and wheat stimulates endogenous opiate receptors [2]. But, if you want to influence brain chemistry therapeutically, eating sweets is probably not the best approach. Good luck!
