when someone calls you there everything it means that with out you they are nothing which also means you are like a power source to them they need you they love you very much to say something like that to you

Answer

The above answer is exactly true. When someone is your everything, with them you can get through anything. Without them, there is no light in your life. When you truly love someone they are your everything. Without them there is no joy, no real happiness, or the emotional intensity that such love adds to your life.
