Why do i feet depressed when i drink coffee?

Allergic? Lonely?: I can imagine a range of emotional associations with narratives/story plots that could be sad - like missing a person you drank coffee with or a whole time in your life, or worrying that it's doing you physical harm. Also, there are folk with a caffeine allergy and one of the possible symptoms is depression. Think about where to start, but if you want to drink coffee see a therapist or allergist.
