Well this is interesting...
What you post... and how you post it... on Instagram... can reveal how depressed you are!
Post in black and white? Photos with just solo faces? You might be depressed.
Like and comment on a bunch of photos of people you want to impress or whom you want to see your 'engagement?' What does that mean about your depression?
Post sunny filters? What does that mean?
Read the story at the link for more... and then, go check every photo you've posted to Instagram... because people may think you are all depressed and in the feels and stuff!
