Founder Depression Research Survey

Many people use the words "depressed" and "sad" synonymously. If you're bummed because you didn't get that big client, does that qualify as "feeling depressed"? If you want to study depression in the clinical sense, it might help to give a specific definition to help guide the survey taker.

I wonder what you are expecting to make out by asking these (specific) questions. They seem too little to let you make anything out of it. I would be really interested in your thought process behind these questions.
