Age: 20; Height: 6'1; Weight: was 160 lbs 5 months ago now 145 lbs; How can I tell if I'm depressed? (Especially when when these online diagnostic tests were written for the lowest common denominator) I've lost about 15 lbs since the last time I weighed myself 5 months ago. Some days i just don't eat. I'm irritable. I always procrastinate. I try not to think about where my life is going, but I usually end up lying awake till 2 in the morning thinking about it anyway. I can easily sleep 14 hours a day, but it isn't restful sleep. I'll sleep for about 5~6 hours straight then wake up every hour and a half roll over and go back to sleep till I'm absolutely forced to wake up. Even then I'm still tired. I am not active at all. Have little energy. Think depressing thoughts when my mind wanders. Occupy my time with escapist activities like watching tv/movies or to a lesser extent in recent years reading. I have noticed over the past five months I shy away from social activities, due to the anxiety of being judged. I've had days where I interact with only a few people and these interactions are as short as I can possibly make them.
