The Leo Sun squares Ceres in Taurus, at 1 degree. The drive for recognition and personal expression clashes with basic nurturing and sustenance. The square is an active aspect, creating tension that demands resolution. So the results could be overactive nurturing, but for the wrong reasons. For example, "force feeding" someone your care as a way of getting attention. Conversely, self-confidence can be undermined by a loss or absence, as you go hungry.
If there's something you're missing, remember that Ceres in Taurus encourages you tend to your own garden. The shadow side of Leo demands attention, but the higher expression of this sign involves self-sustenance by finding your true purpose. This is the light that draws others in. Use the tension of this aspect to express that purpose.
