I don't think that the down arrow means that you are depressed, it could mean various things like the patient is in a down mood (like just upset), or any number of other things, it's very hard to tell what the note meant without talking to the doc that made it. Is there another reason you think you maybe suffering with depression? If you were suffering from depression and they diagnosed you, they would have informed you of the diagnosis- did they mention anything of the sort?
