According to Wikipedia, 'sadness' is a feeling of being alone or lonely, which can feel as a "severe pain related to sorrow", and which results from something negative happened to you. Sadness is when your mood is temporary lowered, whereas with depression you will have the same feelings but which are more 'chronic' (i.e. repeat on a regular basis).
