It takes an intelligent and a person who is up to their level to really understand them. Life is generally hard in the Capricorn world. They struggle hard to get what they want. And a lot of stress comes from that. Capricorns are depressed because they are private people and keep everything to themselves. Sometimes all that anger and stress bottled up in them makes them so emotional when they haven't unleashed it all out. All they really need is a loyal, trusting and understanding friend to listen to them. Unfortunately, not many people are at their level to completely know who they really are.
