Ok this doesn't sound very good to me

When did you have your last physical, and when did you last have an eye exam?
I'm sorry you put it under depression, and yes, that does occur, but not when you can almost pinpoint when it began, imo. Did your stress and depression begin after a certain event that this could be attributed to? If not, I would be sure to give all that info when you see the doctor. I'm thinking doctor will order some tests. I hope it is "just" what you say, though.
