I find a feeling of emptiness comes from not being busy fulfilling my purpose that I was placed here for.
Are you busy looking for opportunities to do Chesed at your job. To make everything you do there into a Kiddush Hashem. To be at least be osek in doing your job l shaym shamayim, bringing home parnassah to raise ovdei Hashem.
The same when you come home.
I find that a feeling of emptiness comes from making myself the focus of my thoughts and actions.
