I feel like Dysthymia(from what you describe) tends to be my 'normal' state...then of course sometimes either due to stress or even just sort of randomly the depression gets really severe, and have certainly been suicidal over it....I also have had anxiety issues as far as I can remember and PTSD from something more recent. But yeah I am not really ever feeling like I am totally without the depression its like its always there even if just more lingering in the back of my mind.
