Are you on any medications at the moment? Some medications for depression or bipolar can cause emotional numbness.

Everyone's depression is individual. You don't have to be crying all the time or harming yourself to be depressed. Sometimes its just the feeling that nothing really matters and emotions are lacking. Mainly, if what you are going through is effecting your life in a negative way, then you probably are depressed and if you don't have a therapist already, you might want to get one.

You seem to be a spectator in your own life instead of a participant. That is no way to live. You aren't being lazy. Depression saps your energy, leaving you unmotivated and feeling like you can't move. Everything happens in slow motion. Until you can find the reason behind your depression, when its because of an event or because you have a chemical imbalance, you can't fix it. Try going to a professional and see what they can diagnose.
