A donut and depression are the same. Both have nothing in the middle, and the other is nothing is left if you leave it for too long.

Hey, listen up buttercup. This joke is about how a donut and depression are similar. See, a donut has a hole in the middle, which is like the emptiness you feel when you're depressed. And if you leave a donut out too long, it gets stale and nobody wants it, just like how depression can make you feel worthless. It's a simple joke, so try to keep up, alright?
