How Do You Write Fiction When You Are Emotionally Dead?

Is it possible to write stories full of feeling and create emotionally-relatable and compelling protagnists if my soul is dead?

I don't mean dead dead.

I just mean I've repressed my emotions for so long that I don't know how to feel and express them.

That's why I sit at my desk and and shout at myself, "Feel something! Feel something, goddamnit!'
