Depression is when you've been under enough stress for enough time (which for many people takes the form of anxiety) that your body starts pressing "snooze" on those emotional signals that are trying to spur it into action. It feels hopeless that it can satisfy what they're asking of it, so it starts to suppress them. While the two are different - opposites, in some ways - they very frequently coincide and feed into each other circularly. They're also extremely common and can be overcome through therapy, possibly combined with medication. If you're dealing with them, know that it's okay and normal, and see if you can find a therapist to talk with.
