I'm sorry I don't know the answer to your question. The only thing I can say is that, based on my own experience, when I am on the computer (or watching TV) time tends to pass quickly for me. Beyond that the only thing I can say is that perhaps your inability to find interest in anything is a symptom of your depression. This may be something that would be worth looking into with the help of a mental health professional... perhaps a counselor or therapist, if you're not already seeing someone. My best wishes to you though...
