Is there such a thing as high functioning depression? On a recent PHQ 9 score (depression severity index used in the UK) I was graded as severely depressed. I get out of bed every day, go to work, enjoy my job and can take care of myself- I just feel generally low all the time with no cause. I've got friends and family as well as a long term partner, and I know realistically I would never do anything serious but I do have SH urges and occasional episodes. I'm wondering if my mood is not actually as bad as the test would suggest, unless high functioning severe depression is a thing?
