Depression does that! Its totally the depression coloring your world grey or black.Do you see a therapist or Dr. ? I don't know much about you yet but I wonder if you are on any meds? You need to get some help so tht world turns to different colors besides black and grey. I always felt with mine it was like a shade drawn over my eyes. I could feel the depression lifting when the shade went up. It was like I saw the world differently and it was all bright and clear.
Its time to top living like this and get some help. And if you are, then the meds need to be adjusted so you find some happiness which you deserve!!
