Everyone has different breaking points. What if the love of your life leaves you? They are you WHOLE life, your everything, your world, the other part of you. To some people it's like, oh well your partner left you, deal with it, don't kill yourself over it for feck sake. But to you it's the worst feeling in the world. Your sole reason for living has gone just like that. You can't breathe, you can't think, you can't feel anything. You were so wrapped up in them, that without them you are nothing. They say don't make someone your everything coz when they are gone you have nothing. But if this happens, then you have no reason to carry on.
