__________________________________________________
1. Felt sad, down or miserable most of the time? Yes /No
2. Lost interest or pleasure in most of your usual activities? Yes /No
If you answered 'YES' to either of these questions, complete the symptom checklist below.

"I'm a failure"
"It's all my fault"
"Nothing good ever happens to me"

This one is from Beyond Blue which is supposed to be pretty credible. But i still think these are a bit too overzealous with diagnosis, but they still give you a guide.
