I lived with a depressed person for 11 years so I know its very real. He would sleep as many hours as possible then get up to spend his waking hours trying to get as drunk as his body could tolerate. I used to think he was using depression as an excuse to get loaded everyday and was being weak. Now that I look back I see how messed up he really was. No amount of motivational talk from me or anyone in his family helped. No matter how bad or good things around him got, he just got deeper and deeper into his own head and addiction. It was sad to watch.
