I feel empty most of the time—does that mean I’m depressed?

Like not carefree or full of life etc.

Just empty. I thought it's something a lot of conventionally smart people feel.

Now I wonder if it's depression.

I always felt smart people are always unhappy. Too much thinking etc. But maybe not necessarily like I wonder if there's more to it than that.
