I think only a doctor can give a true diagnosis.

Too easy to be going through a bad patch for a few days/week/month and assume you are "depressed" then when you genuinely believe you are depressed, you blame it when you feel un-motivated or tired or whatever.

Ive had times where ive felt shit, seemed like things aren't going the way i want them but then i realise thats just life and get on with it, only you can change how you feel, just a case of roughing out the bad times to get to the good times.

imo.
